Hey Boogieman, you rascal sonofagun teenager !
Yeh, I know you're 34, but I'm 55 fso I can say "I saw things you hooomens..." etc.etc. and shake my corncob pipe at you.
Fisherman sailor style !
Trust me, I am still healing from a ...
"
35mph double somersault with my legs folded like a puppet when I landed on my back in rush hour traffic" pretzel...
AND
I actually walked out of the hospital on my own two legs 36 hours later.
St. Peter and St. Rocco (to whom I am oddly devout, me, a semi-skeptic archeological atheist...;
http://en.wikipedia.org/wiki/Saint_Roch) told me my guardian angel had a nervous breakdown, he was in midair trying to keep all my bits together as I was gliding through the air over cars passing by.
Anyway, the GOOD thing is you're telling us about it.
Let me tell you, you were most probably hit by an animal (deer?) that slammed into you from the side, so you lost control but never actually SAW the critter.
If it wasn't a deer, it may have been a boar, but if it was, BOY were you lucky it didn't goad you !
Any chance road signs such as these are common in your area ? North California ?
Anyway, heal up fast, and consider fixing the bike and re-registering it in order to get back on the road... soon !
