It's been a while some we were on dedicated bike trail for any length. Back in Aspen, I think. Today's ride covered a lot of trail on - I think - the same trail line as the trail into Carbondale: the Rio Grande Railroad. In a few spots, we actually passed old rail segments, exposed when the paved path turned to meet a road. As usual, the rail trail was very flat and covered some pleasant suburban scenery. It's been a little funny: this trip covers a lot of wilderness and occasionally routes through cities, but we rarely encounter suburbs. The cities just kinda peter out into farmland.
