Same for Tommy2Steps. Some people see a directional trail and they're compiled to ride it the wrong way.
I have to admit I almost rode down it last year when doing a Crest loop from Park City, I somehow decided it would be a good call to ride all the way to Canyon's base then get back up to Mid Mountain and ride back that way. I died at around the halfway mark since that section of MM isn't exactly flat and mellow. Turns out there's no legal way to drop off MM between Alpine Lake and Spiro though. I was so cooked when I got to Armstrong that I took a long hard look at going down it. Couldn't do it though and slogged the additional couple of miles to Spiro.
