"We" means community?
Who is short $42,000? The thief is never "short" of any money. It must be Bitcoinica customers.
Do you think this community is going to forget that you spent $42,000 of their money? I would suggest (not that you follow them) that you sell some of your assets and pay it back in FULL.
Edit: You actually spent more than $42k on your trips and whatever, but you are lucky the price of bitcoins has climbed so much...
