Greg:
Here, ice normally forms in Dec., and leaves in Mar. It'll be interesting to see what the trout do in my pond this year, they're eating AM 600 once a day. ADF75 feeder. Fan set on high; if I feed for 4 sec duration, there is feed left on the water, 3 sec duration it's all gone. I've got the feeder hooked up to a lawn tractor battery, and that hooked up to a large solar panel, the type that you would see on a roadside construction sign board. No battery problems providing I remember to remove any snow that falls from the solar panel.
