I chastised a friend for getting so upset after losing half a dozen travelers checks on vacation. Get a grip — it’s $2 worth of paper. If you can’t afford to replace that you can’t afford to be on vacation.
For me, I think the concern with Travelers Checks is the potential loss of money from your account, if someone is able to forge your signature on them, and how that might potentially be used to tie you to other events or crimes that may have occurred.
