What to bring
Bring a cooler with favorite drinks. Bring plenty of water.
Have sandwiches and snacks for all days
Canned or fresh food for dinner.(please check "update" for a dinner option)
If you have a camping stove - bring it for hot meals in the evening.
Bring camping chairs if you feel like it - beats sitting on the ground.
Bring a camping table if you want - makes preparing food easier.
Wear comfortable clothing. Bring hiking boots as well as cool shoes.
Definitely bring camera and video
You may need a tent (don't spend more than $60) - since wind will shake the tent and make noise, I prefer to sleep with tarp, air mattress and sleeping bag on the ground without a tent (but I always carry a tent in case it rains).
You will need a sleeping bag (don't spend more than $60 unless you plan on snow camping sometime soon),
You will need a sleeping pad (foam or inflatable) - Get a wide one rather than a narrow one. The big cheap inflatable matresses tend to go airless unannounced - so, I prefer thinner self inflating matresses.
Unless you are used to sleeping on a cot - I do not recommend them!
A sleeping bag with a pad underneath is much more comfortable and leaves you more room to move.
There are 10 million other things that you must or could bring (but maybe you shouldn't) - it depends on your personal needs. My recommendation: Travel light!
Clothing? Bring comfortable clothes - temps will be in the mid 90's during the days, but can soar above 100 F.
Gas? No easy answer to that one. Most modern cars have a pretty good range and will get from gas station to gas station without running dry. If your car is a heavy drinker, you should plan of having 5 gal extra with you.
Expect a range of about 200 miles between fill ups.
Maps?
GPS? not really needed, but they are fun to have
Phone? Your cell phone does not work out there.
Satellite phone? A must have, if you have to report to your boss (wife) daily. I carry one for security reasons.
