innovative geocache that required finding a remote control near by, which triggered a doorbell. The cache needed to be located by sound. To open the cache you then needed to pull out the wooden dowel, which released the bottom flap!
from amanderbee: There are a series of caches in our area that are "gadget" caches; all are birdhouses and all are pretty easy to find. The tricky part is opening them! Each birdhouse is rigged to open an unusual way. I like puzzling them out and the kids love the swag inside. ;)
