Small valuables in a soup can with a screw on top. If they want to haul away 30 cans good on the hope one contains my cash, they earned the couple hundred I sometimes take. I try to not take much cash and use a debit card where I can.
Large vauables I try to leave at home but if I take them, they are covered under my $3000 contents rider on my insurance. Video camera is about the only semi valuable thing I take ocassionaly. I store it under the bed which I have a padlock on. Enough to make it difficult for lazy or oppurtunity crooks but not going to do any damage I can't repair easily if they are determined.
