Another warm mid 50's degree but overcast day in Maryland at the BWI Airport Trail. This is what they call true urban style MUSHing as we were in a relatively busy populated area. The trail follows some roadways but has its own dedicated area sometimes paralleling the road but never really on it that I recall just crossing the roads in some areas. As you can imagine being so close to busy areas and roadways we got a lot of attention being a Dog Sled on wheels with a girl playing guitar and singing to the Dogs as they roll along! You can't make this stuff up this is the REAL DEAL!
