My KTR secret weapon

Since I will show up to the KTR without any sort of acclimatization to the heat I figured I need some sort of edge and I think I may have found it:
I considered a handlebar mounted misting-fan but that might result in the inadvertent misting of a fellow racer and the rules of KTR clearly state that "no outside support should be accepted". I would hate to be DQ'd for inadvetent misting.
