I've had those critters all over me mountain biking in NC. They love spanning trails. Harmless but ugly.
It looks like the dreaded collywobblous horrendus related to the also dreaded Southwestern polkadotted snow snake. Both are usually found in higher climes but will occasionally descend into lower altitudes just to scare the living shit out of pussies that fear all spiders and snakes. Their little laughs are outrageously funny to hear especially when teamed up. :up:
