GOLDEN — It was a warm, sunny Ride the Rails Saturday morning at the Colorado Railroad Museum. My family and I entered the gift shop to get our tickets and I realized I wasn’t the only one who’d decided this was a good day to visit Golden. Only minutes after they began boarding passengers on the Rio Grande Southern Galloping Goose antique locomotive (the museum opens at 9 a.m., but the rides begin at 10 a.m.), the main parking lot was already full and the admissions booth was swamped with rail buffs of all ages. We usually venture farther afield on our weekend adventures, but sometimes, the low-hanging fruit of a trusty, nearby destination (Golden is only 15 miles from downtown Denver) is just the thing.
