Moonshine, sorry to hear about your crash. Glad to hear you're not too badly hurt.
I crashed my Zuma four years ago at the end of the longest ride I ever made on it (a little over 30 miles). I'd taken a shortcut on a dirt path I'd been on a hundred times with my mountain bike, but the Zuma is no mountain bike. Going about 10 mph, the front tire slid out on a loose sand and gravel turn. I went down instantly, landing first on my lower right knee, second on my right shoulder, third a pretty good whack on the right side of my helmet. The Zuma is a heavy bike and it really ground my knee into the trail, it looked like hamburger and was bleeding pretty badly. I rinsed it off with my water bottle and wrapped my bandana around it. The only thing wrong with the bike was the chain came off, so I put it back on and rode the last 2 miles home (thanks, adrenaline). I thought maybe I would throttle it home but the battery was on the last dregs, ugh. When I got to the ER they x-rayed my knee to make sure they got all the gravel picked out, also x-rayed the shoulder and kept checking me for any sign of concussion. I left with 9 stitches on the knee and an arm sling due to acute AC sprain (separated shoulder). 36 hours later I went back to the ER because the knee laceration was infected. I spent a few hours getting IV antibiotics. They put me on 2 types of oral antibiotics and I had to go for a wound check every other day until the stitches were removed. It took 8 weeks for the laceration to heal completely and about three months more to restore flexibility to the knee; it was well over year before I could kneel on it. The shoulder took 8 months to heal and still acts up once in a while. The ER bills were staggering, over $7500 as sent to my insurance, and I had to pay a $2500 out of pocket. The whole experience sucked but it could have been much worse, so chalk it up to experience, and ride extra safe!
