Ditto on being a little late. Another future option is High Bridge NJ where there are about 12-15 nearby caches including 9 along a 2.5 mile stretch (5 mile RT) of the Columbia trial which passes through the Ken Lockwood Gorge. This is a beautiful hike or bike. Here's a link to the cache on one end of the trail: High Bridge
Con-cache-ulations SF!
Little did I know that on my second day of caching when I ran into you in the Sourland mountains that I was in the presence of such a masterful cacher. Good luck on the next 5000!
I've taken my GPSr a number to times into various countries in Europe and Canada and never had a problem. Shouldn't be any different from a cell phone, PDA, or computer. The only problems I've had is being spotted by police in who've wanted to know what I'm doing.
Bambi,
I don't know if you're looking for something more original, but there are a series of state quarters here in the US, and you might want to use the NJ state quarter. It's not real big (1" diameter).
