Long before we were Sunday morning bicyclists, we were Sunday morning joggers.   This Monday afternoon’s bicycle outing to Goldrush celebrated the visit of a distinguished alumnus of the jogging group, visiting from Denver.   With its high ceilings, brick wall to the south, and narrow layout, the shop conveys feelings of an earlier time in the northwest.   There’s some variety of seating, but the narrow floor plan doesn’t allow for many soft seats.   Still the ambiance is quite comfortable as we appreciated the old-time touches.       2601 NE MLK Jr. Blvd.
