I run into people saying this a lot. By this token, I could say to a lot of people, "You stay out of the park? Is that because you can't ski?" C'mon Bush, it's just a gosh darn preference.
Yes, I cannot ski bumps without poles, however, I see them as retarded. To me it would be like taking a Ducati 1098R to Laguna Seca, and then having someone say, "Okay, we all know how wonderful this track is, NOW TRY IT WITH SPEED BUMPS! IT'S GONNA BE SOOOO FUN!"
I would say it to anyone who stays totally out of the park or at least isnt comfortable with a small amount of air as well. well unless they were an actually a student of mine. Your reference really isnt valid about laguna seca cause skis are not bikes and good skier can ski bumps on nearlly anything. A street bike isnt made to be jarred around.
If you learned to ski bumps I doubt youd hate them, in fact there is only one person on here who I am sure can ski them fine who doesnt like them and that would be Upracer. You on the other hand seems like you have alot to learn :)
If you learned to ski bumps you would be better everywhere on the mountain!
