Heading out to San Diego in December to visit some friends and want to check out the dunes (Glamis area probably). Renting a SxS would be ideal because i dont want to ship my car out this time. Plan to do that next year sometime but for now a day on a SxS just to check it out is all im looking for. Can anyone recommend a place to rent? Any other useful information for me as a first time visitor to this area?
