so sorry to hear...healing wishes to your mom!!!

btw: i was off the bike for MONTHS!!! and thought it was gonna be a miserable return but believe it or not...i did 30 miles ON HILLS and felt GREAT!!!! ok a little sore but i won't say that too loud!
your body bounces back amazingly when you get back to the swing of things...i am glad you are there for your mom...

pedal on...no matter how many miles!!!
