RE: my season might be over..
Plant leg or kicking leg? Keep your head up, it's not that bad. You'll probably go see an orthopedic specialist and have to have a knee MRI - they'll know more at that time. Even in a worst-case scenario, most knee surgeries are minimally invasive and the recovery times are relatively short (compared to what they were in the past).
You'll retain some mobility, and you'll probably be able to make it out, but you might have to stay close to the car oruse a ground blind or keep your leg immobilized if that's what the doctor orders. Call your local warden, and he may be able to issue you a special permit that would help you utilize motor vehicles, etc... Also, they're "in the know" with a lot of farmers, and he might be able to hook you up with somebody who has a good hunting spot for a guy with a bad leg.
My hunting buddy was an NCAAlinebacker with ACL/MCL injuries to both knees that required surgery (one in high school, one in college). It never kept him out of the woods, so that might help your outlook a bit. He still complains about joint stiffness in the cold, but it hasn't slowed him down.
Either way, that's a tough break, JT - just don't get down on yourself. Sports injuries happen to everybody sooner or later. Just work through it and you'll be fine.
