I've pretty much built my whole life the last couple of years on mechanisms, practices, and schedules that allow different hats to be worn: Dad, friend/husband/supporter to an almost doctor, cancer researcher, bike rider, and doctor-in-training.

One of the struggles I've found myself in regarding the Columbia cycling community, is not making it to many group rides. Most are scheduled around 8-5 type jobs, which unfortunately doesn't apply too me. Plus, from about 4:30 until 8:30 every night, I'm busy wearing an apron.
