Ouch! Glad your ok DD, next time you better leave the bike riding to the grandkids. 8)
I had a similar experience but it was on my younger cousin's honda Z50, I'm a big guy but I just couldnt resiste the temptation to look like a total idiot on that little deathtrap - so off I went.
One wheelie later my azz was on the pavement quicker than a cat could lick his a$$.
My elbows and right knee took the majority of the blow, I had road rash from my hand to my elbow on one arm, half way down the other and a huge gash on my knee that hurt like the devil - it was kinda hard standing up and trying to look cool after that one, but I managed...lol
Stood up and said out loud, "now this is what you dont wanna do".
