Dehesa Rd is not a desert, it has brush and plants everywhere, and is especially lush, damp, and pretty in the spring months of Feb, Mar, and Apr.
Semi-arid at worst, and even true deserts like Phoenix and Las Vegas, have plenty of flies let me tell you.
Yes I agree, I was trying to point out to VRWC_minion that there is plenty of water, housing, creek beds etc. in this area.
