I went to Spain last summer and it was great, but I went with school so it was really easy since I didn't have to worry about lodging/cost etc.

I camp quite a bit in the States, so I could easily be just as happy saving some cash and camping when I go to spain.

I'm not familiar with the campground system in Spain. Does anyone know of campgrounds around the major cities where I could stay and then drive into town during the day or something? In rural Spain, do you think landowners would allow me to set up my tent in their field (out of the way and in a corner, of course) if I didn't mess things up and offered payment?

Has anyone tried anything like this or have any advice? Thanks.
