I'm always changing my mind about what counts as "my favorite bike ride in Albuquerque," but I always return to the Junkyard Loop. Down in Albuquerque's South Valley, it takes you past the city's sewage treatment plant, a bit of infrastructure not to be missed if only for its pedestrian grandeur. It gives you a sense of the scale of our poop, a fact reinforced by the fact that it's the largest tributary on the Middle Rio Grande.
Around the back, the trail runs up behind the city's junkyard neighborhood, another reminder that a city this large has a load of crap to get rid of.
Treasure, for a moment, the old VW vans.
