How often do you have critters come in after an hour? Do you call continously for the few hours?I usually give a set a few hours and if nothing seems to be going on I'll move. If I work one early in the morning sometimes I'll come back in the evening and work it again. Some people may have a more exact method. I really don't so I have to go off what I know. I'm not familiar with VT terrain or laws. You say you don't have rabbits but that's ok. There are other prey species I'm sure. Chipmunks or something maybe. Calling in an owl means you're on the right track. Can you use bird wings or anything where you're at as a decoy for visual stimuli? Sometimes just a turkey feather hanging from a string on a bush is enough to keep you from getting busted.
