Update

We are back from a hectic and fun two weeks in Michigan. Mac and I really are appreciating Florida more now that we have had some big-time experience with snow and freezing rain and sub zero temps. We got to see Eddie, Brady and Evan play some hockey. We were sick the entire time we were up there, but we had loads of fun anyway.
I got some great news today. I found out that I may never need knee surgery. There will be a lot of tweaking involved to keep me out of pain, but the cartilage is not degenerating. I will have to keep up a vigorous exercise schedule and I should lose some weight to give those knees a break, but basically no surgery is good surgery.
