I scar very easily (Mark knows this) so between the bugs and sharp schist found at Rumney, I have been wearing long pants to climb there for years now, no matter the temp or humidity.
i see. that is a seriously bad ass heel hook! though not sure if its a great explanation, as i have never gotten bruises and scars up to my knees from using my heels haha... black flies on the other hand i get, and you are right sir they don't look too bad
