Maybe it is because I grew up in pretty much as far south east as you can get in the bayous of Louisiana, but I personally think squirrel is one of the best meats I have ever eaten. I personally like to rotissery it after soaking it in hot sauce for a good while. You can also wrap it in bacon, but that part isn't necessary.
Haven't tried one of the gray pine squirrels but I do have a great receipt for squirrel pot pie. Usually boil or fry the squirrel then debone it, throw it in some gravy with veggies. Nothing better. But heed the warning to only kill them after a good cold spell. The fleas are nasty. And what ever you do don't burn the fur off them they are super easy to skin. Your neighbors will appreciate it.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
