One thing that could get annoying in the LI geocaching scene is the "bison tube hanging in bush or pine tree" style of cache placement is starting to become popular. The foliage can hide a tiny cache very well, leading to a needle in the haystack situation. So if you aren't lucky enough to see it quickly, it could be a tough search. I got a bunch of those today but after the fourth one, I was ready to pass on the rest. Fortunately, there weren't any more like that.
Dinner was in Flushing Chinatown, which is still worth a side trip.
