Will be traveling West on I-90 to Custer State Park. Would like to see the Badlands, but don't want to take all day. Planning to exit I-90 and enter at NE Entrance, taking SD240 into Wall, then continue on to Custer. Are there any hazards/issues I should be aware of: steep/narrow switchbacks, etc.? Rig is Toyota Tacoma towing Aerolight 19L (24'). July 27
