Anyway, if you go up to any mosque and find a person you can ask, hey is it okay if I check this place out? Can I join in the prayer? Unless you meet an old uncle from the old country, they'll probably welcome it.
The mosque I go to now, in Edmonton, we have this guy that comes for the potluck. One day, the prayer is starting and I tell him, let's go pray (we were cleaning up) at which point he tells me he's not Muslim! Anyway, no biggie, he continued cleaning up while we prayed :)
