Many thanks for the suggestions so far - keep them coming!

I like the look of a couple of the locations that are closer to downtown than Anza-Borrega - but, I'm coming in from London - and for the first 2/3 days that means I'm usually awake at around 4am, so if I get my act together I could make a slightly longer trip...

I'll have a rental car.

Any recomendations as to where I can get 6x6 and 5x4 E6 processing done in SD?

Thanks again
Richard
