To Hoolie and TT120 - thank you! That's exactly the kind of info I was looking for
To Bob - I mentioned in the post I'm in the UK, so I don't understand why you'd need any more location info than that to be able to answer my question, and as far as your comment regarding 'Eurotrash/Eurotreasures', frankly that comes across as downright rude and offensive. You know what, that's the kind of judgemental attitude I really wasn't expecting to find here.
Thanks for checking back. When you don't fill in your eplaya profile, which you hadn't at the time, the context which your home location adds to your individual posts is lost when the thread goes to two or more pages, or you post on a different thread. A more descriptive thread title might have helped as well.
You also gave no indication you'd glanced at the volumes of material on the main website and the eplaya, little context wrt the nature of your previous camping experience (wilderness camping versus car camping versus RV camping), and whether you intended to go the conventional route at Burning Man (car camping, pretty much), extremely lightweight for air travel & hitchhiking, or intended to have a rental truck or RV for support along with heavy cooking gear. Knowing what you considered edible on your previous trip here, or in the UK in general, might have helped. If your tastes are very specific, and you arrive in Reno with only hours to shop, you might be disappointed. If you're arriving in the San Francisco area with a couple of days to prepare, of course you'll have more options.
Don't take it personally, it's not about you. Happens every year.
Actually, I've long thought the main website could use a guide to semi-ultralight camping specifically geared toward Eurotrash
, pardon, jet travelers who end up hitchhiking or renting dinky subcompact cars in Reno. Can you suggest an alternative moniker?
