I think you would be surprised,i used to travel to Loftus road when Wasp's played there and i still travel to Wycombe to see them.We used to get very good attendances at times also.
It was sometimes a great weekend SFC Saturday,Wasps on the Sunday.
What was great about it was the completely different going to Rugby,have a beer wherever and whenever you like,great entertainment and atmosphere, reasonably cheap tickets to.
Don't knock it till you have tried it.
