It's a free country--take your dolls wherever you want to! Taking along a camera is a good idea if you're self-conscious, though.
I'm 46, and I've begun taking a doll or two along when I travel, so I won't miss them so much! I hate to leave my girls for a whole weekend.
But the only place I've actually taken one out to is AGPC, and lots of people were carrying dolls around in there!
