Not only can you practice with your bow all year you can practice deer hunting all year too just not shot one out of season. You will learn how to get them to come close to you, learn where you need to place your stand/blinds. Just keep in mind the summer trails may not be the ones they use in the fall.
I'd get rid of all that gimmick scent stuff and just make sure my boots were clean, not carrying gasoline scent and other stuff.
