I hate that. But if you suck my wheel without me knowing, you run a huge risk. I am a constant nose blower! (Just the left nostril - don't ask me why.) Many's the time I have unknowingly blasted a wheel sucker I didn't know was there!! (Sucks when I am riding with friends and they happen to be quiet and I haven't double checked to make sure they're there before I let loose, though.)

So maybe something to try next time? Pretend you don't know he's there and fire one off...!
