Congrats to your son, @
joeyduck. I keep telling my daughter that it's time to take her training wheels off, but she's pretty tentative and insists we wait until next year.
Had a nice pre-work ride this morning. Legs are a bit tired after a couple longish weekend rides, so I took it easy. Beautiful weather - cool, sunny, no wind. Need to track down the cause of some creaking and squeaking in my fixie - it's probably (hopefully) the chain. I don't think I've ever lubricated it!
