I posted earlier about a trip I am planning and now the details are becoming together a bit more. I was planning on doing some camping in National parks along the way (starting with: Death Valley, Mojave, Grand Canyon, Zion, Arches). I'll be setting of the start of April from LA so am, hoping to miss the main summer tourism for this bit.
Is it recommended to book camping sites (can you even do this if there's a hiker/biker site?), I would like to avoid this if possible so my itenary is flexible. If the campsite is full, is it normally okay to ask people to share a pitch? I'm hoping that just myself with my tiny tent shouldn't be too much of a problem. But I'm used to the UK where it's normally just a field rather than defined areas, and you can just put your tent whereever it fits!
