Just as subject suggests... it would be awesome to combine the efforts of the Alltrails.com or WTA.org sites to be able to search for a trail, then DL the pocket query of caches along that trail (with a certain offset of distance from the trail route). Seems like it would be an awesome thing to do, and quite a useful feature for premium members.
Thanks!
PS: I also would be willing to assist in the coding as well.
