I just got a trail cam from Wally World. I think it cost $60 or so. It takes 8 AA batteries and a role of film. It is programable to shoot up to 9 frames per movement. And you can set the delay between movements from 1 to 60 minutes. Here's what I want to know. Right now it is pretty chilly here. Probably has not gotten down to zero here yet, but has gotten pretty chilly. I don't ever expect the cam to get much above 30 degrees until March. How long can I expect batteries to last? 3 days? 2 days? A week? I really don't know and there is not battery meter except a light comes on when they are low. Remember, it takes 8 AA's.
