in the middle of an epic ride today (105 miles), there was a group of older guys and gals blocking the path. they completely saw me coming as one lady bellowed (yes, bellowed) "did we leave enough room?" seriously? so you know you're blocking the path and instead of moving you joke about your ignorance. my response, "almost!!" i was not happy. she thought that was funny and chuckled her bowl full of jelly.
yes, some roadies can me silent runners and not acknowledge your presence. but i'll take that over purposely creating a dangerous situation.
