I'm flying to San Diego(I had no choice about going) to attend a work conference until Wednesday. I obviously can't take my weapon and can't fly with a knife but I can take a bright flashlight... worth doing or should I just buy a cheapo knife when I'm there and ship it back to CO before I return?

Some of the conference activities involve late dinners so I'll have to walk back to the hotel when it's darker out(with other people from my office but they're not very aware). The walk is only a couple blocks but I don't like going anywhere around here without at least a knife and California is way more messed up than Colorado... for now.
