Setting out cameras?

Last Sunday I ventured over to the property in Greene Co and pulled the 2 cams I have to end the season. All week it was bugging me that I might be missing out on pics of the bobcat(s) or other cool stuff that might roam through. I ended up with a 3rd camera on Friday and decided that if I make my way back over there this weekend I was going to set all 3 cameras back out and I did that today. So I guess I'm starting the 2014 season early. Last year I set the cams out in late April and I thought that was early enough.  My 3 cams are all different. I have an Eyecon, Wildgame and my newest one is a Moultrie. The Eyecon is the best of the bunch imo. It has a 5 shot burst option and I set it at a place where I believe there will be high bobcat activity. I didn't get to set it exactly where I wanted to but I'll remedy that the next time I go over. I will say this about the Eyecon; with all the pics it took last year the batteries are still showing full power. Even after sitting outside when temps dropped well below zero. The Wildgame burned half its battery life since the beginning of September. The Wildgame runs 8 AA's. I think the Eyecon uses 8 C's but it could be 6. The Moultrie uses 4 C's.  Now I just need to keep myself from checking them earlier than I would like to.  I'd love to leave them alone till the end of April but I know that won't happen.  I can probably let them go for a month.
