Anyone still interested should definitely try to go for it. Brian hasn't started taking deposits yet, so it's quite possible that when "committed" folks actually have to plunk down some serious cash, they may find themselves unable to do so, and slots may open up to others. The best shot to go on the trip this year would be to get on the list, even if the original 12 spots are currently spoken for. (I don't know for sure if they are, just saying "IF".)

So if this opportunity is screaming your name, don't give up before you try!
