In reply to Tom Ripley Mountain Guide:
Cheaper for you than us taking that Euro beating!
Rental cars: Probably about $30 a day.
Gas: about $3.60 a gallon. Our clean ass save the world crappy cars get maybe 25 miles per gallon. SF to something like Joshua Tree is 450 miles. To Yosemite probably 200 miles.
Food: Actually real cheap. If you go to a supermarket and buy your grub look at about 10-15 $$ per day for breakfast, lunch, and probably dinner. Eating out is usually about $7.00 for a two egg breakfast with toast and coffee. Lunches can be fast food from $3.00 to sandwiches at a deli for about $6.00. Dinners in an actual restaurant run about $10 to $15.00 not including Margaritas. If you guys have extravagant tastes you could easily double the costs above. Buy an ice chest ( $20 ) when you get here to store your goodies. Ice is $2 for a 10# bag and you will need 2 a day.
Lodging: Chain motels are about $50 per night unless you are in Las Vegas where you can score for as little as $15 per night. I never stay at hostels since they are infested with hippies and people that want to hug me.
Tourist stuff: Things like the worlds biggest ball of string and the giant thermometer are free. A museum might be $5.00 to get in. There is no culture over here so stick to looking at odd roadkill animals or fiberglass Paul Bunyons and you will do fine and still have plenty of money for beer.
Beer: total shite is about $4 per six pack. What we call the good stuff is about a dollar a bottle when you buy in bulk (12 to 24 bottles). In a bar they will get $5 per pint so "pre-load" out in your car and then wobble in for a lone pint.
Things will cost more in National Parks like Yosemite. Add about 25% to adjust for the wow factor.
Prostitutes: In Las Vegas and Joshua Tree I never spend more than $12.00 for an "around the world".
Health Care: Free. Go into any Emergency Room and drop on the floor. They must treat you. Then when they stick the clipboard under your nose looking for payment, tell them you are from another country and will try to send them something in the next year.
There are no real toll roads but getting into Yosemite etc will cost like $15 or you can buy a pass to all the parks for like $80. Bridges in SF cost some money to cross, but I have no idea how much. Probably a couple of bucks.
Clothes: Walmart togs fit me well and I've never spent more than $10 for Prana-esque climbing pants there. T-shirts with pictures of Kenny Rogers or Hello Kitty on the front go for $5.00.
Gear: Ropes can be had for about $100 to $125 on sale. All the rest is about $40-65 per cam and $10 to $15 for a quickdraw.
Sunscreen: Suncream is $8.00 per bottle but often have a buy one get one free deal going on at RiteAid pharmacy. This is where most of your US trip expenses will probably be.
Enjoy!
