My wife and I are heading up to Yellowstone NP this fall. RV Trip Wizzard is routing us into Cody via highway 120 and we merge with highways 14/16/20 and proceed through Cody finally exiting to the west via highways 14/16/20. So my question is this; are the streets along this route RV friendly? We are pulling our 303 5th wheel, will we get get caught up on narrow streets in this town?
