I don't know the area well enough to be much help specifically, but I know a little about hiding things.

My advice would be that if you're thinking of bringing some along and don't want it easily discovered, put it somewhere people are embarrassed to look. Get yourself some "honeymoon entertainment equipment" and stash it in that. Nothing says "look no further" than an over-sized vibrator. And there's no rule that says it has to have the batteries in it...

(Though considering the weight difference you should be sure to have batteries packed alongside it.)

If you REALLY want to make sure no one looks too closely, make sure it's a little sticky. (think apple juice or something like that) I haven't met an officer yet who'd look twice at a what appeared to be a used and not cleaned sex toy.
