I used to be one of those crazy mo-fos , wheelieing for miles. Can you say S T U P I D!!!
I went skipping across the pavement doing about 70MPH back in 83. I was fine until I looked at my knee. Hey what's that white thing? Oh, that's my knee cap and a good case of road rach in various places, Then the pain hits.
Want to know how they get all the dirt and rocks out of road rash? They scrub, and scrub with a brush. Feels lke getting branded and having acid poured on it to cool it off.
Spent 2 weeks laid up, until I could walk around.

Smartes decision was selling my bike!!!! Too many dogs and cars to deal with.
