All those are good places to find bear. Especially near a water source, as summer comes along and a bear is eating more and putting on weight, they require more water to aid in digestion of berries, and will go to water a couple of times a day. The first thing I would look at is finding what bears in your area are feeding on, find the food source and find the bear. Call down to your local fish and game departement and ask a biologist, or go out in the feild and look for scat. Like an accomplished bear hunter told me, "For the nine months a bear is active, other than the 2-3 months of the mating season when he is looking for a female, he has two things on his mind, sleeping and eating. He is just like you or me, if he wants to sleep in on a Sunday morning until 10:30am he will, but the minute he wakes up, he will head straight to the berrie patch"
Depends on the time of the year around here,right now you could find them anywhere,later in the summer/fall they will be along the streams eating chokecherrys and strawberrys,after the berry crop is gone they go up higher and we start seeing them out on the shale slides,when thet rut we see big boars traveling in the middle of the day.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
