Thanks for the tips. I actually went out to cafe mox to find some sort of container for all the expansions. Found a "sort of" solution there.
Its a very neat space, but when I looked around I didn't see any dominion players. Lots of magic (lots!), carcassone, that train game, and others. But No dominion.
I asked the girl at the front if they ever host tournaments. She said "no", but to email them and if there is enough interest they will. I did, but unsurprisingly haven't heard anything back.
If you ate ever going to be there, let me know and I'll try to swing bybifvim in town.
