pumped the tires to 100 psi after 2 weeks use (pump started at 80psi) and with wind on back, flew to work AM. return home was successful dance with cars/fellow road users (no bicyclists). went to meeting tonite at local library using new lite system, kid there asked me what was the crisis (yellow jacket amd flashing stobe lites may actually have looked like a Police - EMS uniform), told him "just riding around". town changes around here after it gets dark...got that "gut feeling' a few times, but the bike zipped through these areas. a good day with bonus miles attached!
