Finally back on the bike for commuting. Felt great at a mild 29F.

Quick History ... Hurt my knee back in early November, kept trying to ride after varying amounts of time off and every time it hurt. Finally went for an MRI after a couple months. Diagnosis: torn meniscus, possible ACL problem, Baker's cyst. Went for a second opinion, said just meniscus flap tear. Said I could go ski on it with minimal risk of further damage.

Went skiing, knee 90%+. Tried riding over the weekend and felt good. Did a very short run on Monday and that hurt the knee again. Tried commuting in this morning and it feels great.

So, unless something goes to heck, no more running, ... and no stinking knee surgery needed.
