Questions about Quartzsite, AZ

[asirimarco]

After we leave Vegas we are thinking about going through Quartzsite on our way to Mexico. But have some questions
It will be around the end of November first of December so will probably be crowded there.
About camping on the BLM land - do you need a permit? Can you stop any where or just designated places? Do the other people in a desert spot welcome strangers or is there a protocol to follow? Any info will be much appreciated.
