Tough luck brother. Winds will keep me inside too. As for the shoulder, no time like the present if surgery is the final step either way. The PT is more for insurance than anything, have to prove that it was not helpful to make the shoulder surgery a necessity. But, shoulder surgery is generally very effective, especially with the rotator cuff. So, get on the therapy sooner than later. Cuff surgery rehab is a good 3-4 months until your arm will be back to near normal, so I wouldn't wait until summer, or you won't have to worry about hunting next year.
