No sup air sites in Glasgow at the moment or anywhere in Scotland. We (the clan) have one sup air kit we use for training but at the mo its in storage.
There however loads of recball sites and a possible reball centre opening just outside of glasgow at the start of next year.
As for clubs...depends what type of music your into...let me know adn ill tell you.
Pubs, loads of pubs on Sauchiehall street and loads of nice ones in teh west end which is just a short undergroup ride away.
I stay outside of glasgow but i go to uni there so if any of ur guys are students u can always hit the unions.
