alrightythen! it looks like the upper part of potrero varies between 14% and 17%! then it "calms down" some to 9-10%... then gets more normal with 4-5%... then "leveling" out some with 2-3%... then back up to 10ish%.... finally ending around 1% ....

so there you have it! the very hairy upper part IS steep! but we already knew that by virtue of riding it!!!!!!!!!!!!!!! right!?!
