I completed the ADK Fire Tower challenge back in 2012. I've only done four of the 46ers. And I'm also working on the 100 Highest, which includes the 46ers. And if I hear about any interesting hikes I'll do those to. Just a month ago I was near Whiteface, trying to get two mountains off the 100 list, failed again, but right down the road I saw a fairly new sign and parking lot for Cobble Lookout. Decided to check it out and it was worth it. A fairly easy hike a little over 2 miles round trip, to a large overlook that faces Ester and Whiteface. I've recommended it to a few people that wanted something easy with views.
