Day 6 East: Another late start, another tourist day. Started in Gillette WY. Into the Black Hills...really nice roads and beautiful place. I can see why bikers are so attracted to the BH. Traffic wasn't as bad as I imagined, the park service got the flow going smoothly. Out of the BH and I didn't even know that I was gonna go thru the Badlands. It was hot there. Chain is acting up again, checked it and it is loose again, it has a slight kink in at least one link, but also the tight and loose spots are really far apart...seems like the concentricness of the sprockets are really off. Next time the wheel comes off I'll rotate the rear sprocket carrier and see how that goes. Made another half turn of the chain adjuster. Got to Murdo around 7pm.
