Agree with most, definitely don't hang cam in bedding areas, I'd stick with food sources, multiple trail crossings. I'd also say stay away from active scrapes, unless your cam is a no-flash model. I had mine on two scrapes this last season, and had a pic of a bruiser at each one, but in both cases he never came back in the 2 weeks that i left my cam. I really think the flash spooked him. About the buck showing at the food after dark, which happens 99.6798234775%(or something like that) of the time. I'd place a few observation stands and try to figure out where he is coming from, if no success, gradually move farther away from the food in the direction you believe he is coming from. Granted this is not a very easy thing to do. I've gotten a lot of pics of nice bucks in my food plots, but they were mostly from 2 -6 hours after it got dark. It is really a guessing game, especially during the magic time of the year when the big boys are logging a lot of miles. I mainly use my cameras to let me know what caliber of deer I should hold out for, and also determine which does have what for fawns, so when it comes time to thin the herd, i can concentrate on the does with button bucks for fawns.(I've got a wierd bit of logic for that which takes a while to explain)
