I will be entering Yosemite from Hwy 140 (West Entr), last stop being El Portal. After that, I will be driving south to Fish Camp. Do you know if chains are available at the west gate?

I won't be picking up my car from the airport but rather from Fisherman's Wharf as my wife and I will be spending a week in the city and a car would be more a liability than anything else.

The best rate I got was from Hertz - intermediate SUV at USD 240+ per weeek before LWD but not sure if I'll actually get a 4WD. Dollar offers a Standard SUV at a hundred dollars more and I have that on reserve.

National's rates on the internet was rather high.
