The last couple times I've been back was over Thanksgiving; we've got some family in Germany now, so we take that as an excuse to visit Europe for Christmas.
My old neighborhood bike shop was Olympia Cycles near 40th & Hamilton. Now that I think about it, we didn't buy any bikes from them, but I did get a new rear wheel one time, and my mom took my old AMF 20" bike to get checked over & rehabbed before my niece came to visit.
