I can tell you I totally miss it, I raced MX for about 20+yrs until I finally had one nasty crash in my thirty's. I came back and raced a couple more times after I healed up but I wasn't able to race at the same level due to mind games. I figured paying my house payment & taking care of my family was more important than taking a chance of spending my days in the hospital again so I retired from MX. Its all good thou, I open up the R whenever I get a chance at the dunes to get the heart pumping again. Not the same as competing but still fun.
