@nybiker, I'm working with the Hub in Catonsville. The airport loop is the BWI loop. The loop is FINE but I'm just not really sure what the point is if we just go there. If you know Catonsville, the alternate route would be Frederick Rd (that's the busy road)->River into Patapsco, loop around the park, back through River to Frederick (all shoulder this portion) to the Trolley trail and then the bike lane on Edmondson home. Frederick Rd is the only concerning portion.

@shootingstar you are right that Cyclofemme is just a loose organization -- or at least that's my understanding too! I just saw this as an excuse to get some more women cycling in my neighborhood (and hopefully meet some other ladies to ride with)
