Air Conditioning
Air Conditioning... If you're an asthmatic, you understand completely.
I've rolled back into the lot after finding myself on a ride downwind of a farmer spraying pesticide and I have to tell ya, the AC with HEPA in the Ranger was a Godsend.
It's also a Godsend on those days one rolls back in after 45-60 miles in 90 degree heat and 60% humidity.
