Hey fellow Coloradan. Don't you love that kind of thing? Usually happens to me with pedestrains/joggers. They'll come at me two-abreast, taking up the entire bike path, looking right at me and won't move an inch! Now, technically they have the right-of-way (bikes yield to peds), but they had plenty of room if one had scooted in behind the other and I was the one climbing a grade. I would've thought common courtesy would dictate they at least make some room for the climbing biker. I was somewhat annoyed as I approached and yelled "hellllllllllloooooooo!" I think they got the message that I wasn't stopping and quickly moved with an embarrassed look on their faces. They also apologized and we left as friends. I just don't understand this mentality though. I've been "in the zone" too - but it doesn't cause you to tune out all logic...
