expensive sunglasses. bring them or not?

so i have 1 pair of $100 sunglasses. am i just asking to have them stolen off my face down in pats or will i be fine? i really like them but if theres a good chance they will bet snatched i will buy some wal mart specials to bring instead.

same question goes for gold chain or nice watch. is it best not to "bling" out in pats?
