yeah,i screwed up today and forgot my camelback,i sweat far too much to be lax on fluid intake,gets to be hard to drink from the bottles after the water gets hot..the trunk bag i have is insulated so i have been being a whore and stopping at a convenience store and grabbing something instead of carrying the pack..it was hot today...forgot my mp3 player too,the tunes really help when its just turning the pedals over endlessly...i have that advantage of being able to let my attention go slack for brief periods...you are sitting down after all...
