Just some broad generalizations... 2nd season success is slightly higher, and there are 50-25% fewer hunters in 3rd season. There is just a slightly better chance of snow during 3rd season, which helps a lot. And the second weekend of second season can be very pleasant with even fewer hunters out than during 3rd season.
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.
