Well, lower antelope. Amazing place. Hard to take a bad photograph but jolly difficult to take a good one (I found!). The "photographers' tour" must be one of the best local bargains: it's the same price as the one-hour tour but you can start whenever you like and stay for up to four hours, without a guide moving you on. Just turn up with an SLR and a tripod and sign a promise you won't sell the pictures.
Anyway, comments welcome.
