Bike troubles

So, we have been having some bike troubles the past few days. First
was Blair's wheel...lots of issues there, we just ended up replacing
it. Then Gary, and John have been having shifting difficulties. Mark's
chain broke yesterday...and again today.
I am feeling pretty lucky because the only problems I have had are
some easily fixable flats. (knock on wood)
Though we do finally hit a decent bike shop in a day and a half in
Carbondale Illinois.
So its been a rough, steep, hot, humid past few days...still, I am
having fun and wiu prefer to be here than UPS!
