I've been and watched London 1st Team, Reserves and Academy at the following grounds:-
Craven Cottage
The Stoop
The Valley, Charlton
Griffin Park, Brentford
Barnet (The Hive)
Bridgend
Henley RUFC
Gillingham
Harlequins RUFC
St. Mary's College, Roehampton

What other grounds have they played on?

Chiswick, Barnet Copthall, Esher RU, Stamford Bridge, Perpignan, Wycombe Wanderers, Leicester?

We played a game at Esher once (Catalan Dragons I think). Also Bridgend Brewery Field.

Did we not once have a on the road game at Coventry? But I remember that Cats game at Esher very well. Was in on a Tue or something

I went to the Bridgend game

I just remembered it was not Coventry we played at, it was Leicester (vs Hull I think).

We played Warrington in Carcassonne in 2002. I also remember we played at Crawley once and at Leyton Orient too.

We played Bradford at Leicester- seem to remember the club organised coaches for season ticket holders

Did we play a cup game at Kingstonians ground?

Hendon FC.

Are we counting friendlies? If so: Wellington College, Crowthorne (against Swinton). Shortest trip I ever made to a game as I lived across the road from the playing fields at the time.

Crystal Palace National sports centre.

We played Widnes at Aberavon, Port Talbot. We also played at Newport. The academy played a number of games at the Military stadium, Aldershot.

I think I recall Reading and was Kingston mentioned. I've been to all those and didn't realise how well I travelled in the past

Do not forget we played Bradford Bulls at Tynecastle, Edinburgh in 1998. It was part of the "On the road" fixtures, when our host clubs carried out maintenance on their pitch.

Hendon FC - my first ever live game of RL, and the first under the Broncos name v Keighley Cougars.

yes, we playeda couple of early season Challenge Cup games?

Remember a game at the Orient - bloody vertigo at the top of their main stand!!

What a great weekend in Carcassonne that was. Only bettered perhaps by Les Chevaux dangereux de Londres V Leeds Rhinos as the Perpignan club advertised it. The year of the Leeds Elvis look alike fans. Haven't seen French Gendarmes as perplexed since.
We can add the HAC to the list & of course Wealdstone FC where we played quite a lot of games. I'm beginning to think it might be easier to list where we haven't called home!

I have a feeling that at some stage between 1980 & 1984, due to a bad winter with many games postponed, we played 1 or 2 home games in the north to save the team coming down. Widnes would be logical because of Reggie or maybe Swinton. There was also a Lancashire Cup game V Warrington held at Wigan but don't remember the circumstances around that.

Does Crawley Town FC ring a bell for anyone else ?

Also, I am sure that some venues mentioned were 'on the road' games which all clubs had to do, so probably wouldn't be classed as home ?

Has any rugby league club had more home grounds?
I think that’s one record you may hold.

Yes I recall walking to the ground from the station. If I remember correctly, it was in 2001 when we were playing at Charlton and we were drawn at home in the Challenge Cup the same weekend as Charlton were playing at home.

I think Dennis Moran and Jimmy Dymock made their debuts at Crawley?

The first time we played in Perpignan was at different stadium to where Catalans play, I can not remember the name of it but I can still remember the banquet they provided afterwards and the wine tour the next day.

Yes, I was there. A grey and damp day.

It was a Challenge Cup game versus Batley.

I've seen the Broncos at Brentford, Charlton, The Stoop, Crawley Town FC and Kingstonian.
Oh and Wembley too!

Don't think I've missed any.
I never did quite get to Hendon on those wet winter Sundays when we were London Crusaders.

The Dragons started playing at the RU's club's ground ( Admiral Giral?) while Brutus was being upgraded, so it may have been there. There was also the 'on the road' match in Carcassone mentioned by another poster above when your boys beat the Wire: notable debutant for us that day was Ben Westwood.
