When I lived in Boston we never used any of the local stadiums. Sullivan/Foxboro ( now the new Gillette ),Fenway, The Garden, Fleet Center ( now TD North ). It was either driver out to the assembly hall in Natick or The Providence Civic Center.
When I got to Texas, the JW's were using the Astrodome.When that closed and they opened the new baseball stadium in 2000,that was off limits.Being grass that didn't surprise me. They rarely use it for anything else.
Then came the new Football stadium around 2002 and the owner pretty much told them to go jack off. I'm guessing,even if they cleaned it for free.
The old basketball stadium sat EMPTY for a while. Not sure if the dubs took a shot at it,but it is now the home of Joel Olsteens Mega church. The new basketball stadium has always been off limits to the dubs here too,to my knowledge.
But every Feb/March they dump a ton of dirt in the football stadium and have a month long rodeo. BUT, it brings in $$$$, so they could pile all the dirt in there they want.
The brothers would always brag that we got use of the astrodome because we'd clean it for free. I do indeed remember spending one saturday before the conventions scrubbing that place from top to bottom.
They now use two local sports arenas essentially built for local high schools. One for english,one for spanish.
Nothing beats watching a game in Boston. People down here come to games to talk business, or socialize. They sit on their hands and it's Zzzzzzz until something happens.
