What do you do when it's too hot to cache?
You hide them instead.

Driving around in an air conditioned truck looking for cache hiding places is what to do when it's hot.
Use the parking coords to park; do not park on Akron Drive. You cannot access the cache from Akron Drive.
Be stealthy when searching. There are few areas for this to be hidden, so don't give up if you dont see it right away.
