Holding locations for a "Party"

Okay this is location 1.

It's a wide clear area right next to toilets, it is probably the best location space wise but it is a popular picnic spot and only maybe 4km away from the local Authorities, I really wish someone wouldn't complain about sound but I know someone would here.

Pros:

Large space

Close to civilization

Cons:

Near Police Station

Popular spot with local picnic goers

So This is location 2, it's probably 20-30km away from civilization but again it's another popular picnic spot, that being said it is atleast 20-30km away from local authorities and as far as I know it does not get locked out at a certain time like other spots, it is also in a canyon so sound could reverb and echo everywhere for miles.
                     
                                           
                                                           Pros:
                                            Far away from civilization
                                                           Cons:
                                                  In Canyon/valley
                                           Still goddamn picnickers

Location 3 and 4 are only just down the road from number 1, maybe 500 meters or so, but that being said there are less picnic goers down this end of the area and it does also provide some large space for a party (also two toilet facilities) the problems with number 1 still exist as it is only 4.5km away from local cop shop with is a 5-10 mintue drive, but hopefully down here we would get less exposure to the public, problem is this area gets locked out at 6pm or 8pm.
                                                       Pros
                                               Same as location one.
                                                         Cons
                                            Local authorities close buy.
                                            Lock out at sort of early time.


Now why don't I throw a legit party? Because throwing outdoor parties these days takes alot of insurance and red tape and though the Local Government might authorize a folk festival or whatever, I doubt an small outdoor rave would get the stamp of approval so easily.
I'm not trying to cause trouble or whatever, I just want to have an outdoor gettogether in the sun with the local scene, get a few DJ's and have a fun time, no "Drug trafficking" or "Devil worshiping" like ravers are so much attributed too in popular culture, just a fun outdoor event.
