alpine... how long have you been riding? descending can be nerveracking! I was really nervous about it my first year especially... to this day I am careful and don't take it for granted... I have hit stupid top speeds, but only on straightaways...
there is a fast downhill on my commute home... there is a section that is a bridge over a valley below... last week as I crossed there, doing about 37mph, the wind was HOWLING! My front wheel started to shudder... man, did I sit up and start feathering my brakes! Slowed it waaaaaay down...
I have a healthy respect for pavement... and my skin!
There is a fine line between "hobby" and "mental illness".
