I just bought a therma cell also...... I have tried it out yet, but I also heard good things about them. If I get a chance to use it soon I will report back.
It would be nice to be able to practice calls with real birds to see the reactions during the off season! This work thing is getting in the way of my fun! haha
This year I am trying soybeans in a 1 acre plot next to a hay field and a 1/4 acre plot on the edge of standing timber. hopefully we get a little more rain soon!
