Yep. "New York Seaway trail series" hidden by 2 cachers in Chautauqua County in '05 and '06, looks like about 20 are still active. Mostly roadside micros there. This here is all official and stuff, and 75 .30 cal ammo boxes were given out to Geocachers to hide. I was one of them, and I dropped mine in Niagara Falls right on the river, about 2 miles upstream from the falls. So come on out and find it (and the 74 others). But we're a few weeks in, and I'd say only about 60 are placed right now.
EDIT: About 65 are placed now, I hadn't looked in a while. Apparently it's just my region (Buffalo/Niagara Falls) where there hasn't been any new ones in a couple of weeks.
There's a great article in the Buffalo news about this, didn't see it in the paper but read it online. I plan on doing this series with my two daughters !
Do you have a link to that article? I'd like to pass it on to Boots..., who organized the whole thing.
Here's the online article.
