I think I was sort of in that I-70 "group". It was sort of disjointed. I was just trying to get home as fast as possible, my ass was killing me. The seat on the freaking K5/K6 gixxer's is brutal. And I know it's got to be bad, because I've ridden over 100 miles offroad on a skinny mountain bike seat and it didn't hurt as bad as that highway trip back home.
With only 1,500 miles on the gix, that was the longest time I'd spent in the seat to date. I think the gel seat is on the must-purchase list.
