It seems that you have put some thought into this.. and i think we could use another field South of Phx, as there are quite a few North (including Hatfield, Fort Adobe, Fighter Town, the Rebel Union games, etc.) Also, there was another thread posted from some people in Ahwatukee looking for places near by.
It would be interesting to hear what others have to say about the options you posted.

Gila River Memorial Airport sounds great.. but as you mentioned, although not operational, it is owned by the Airport Authority.
Doesn't that mean that you need their permission to use the area?

As for Scottsdale 6 Drive-In, i believe it is too close to the street. I believe that you -have to- stay out of sight if you are going to do this in a rather populated area.

The Evergreen Golf Course looks promising, but who owns that place?

So, is the game off or something?

Until another larger and likely more remote field is found, i am guessing that yes.

Four Peaks is too far.. it is actually closer to get to Hatfield or to the Reb.U. games (Depending where you live of course).

But anyway, the fact remains that we need a good location in the SOUTH EAST Valley -- so if/when someone identifies one, please PM me.
I would be happy to go check it out with you. (Printezis@gmail.com)

Could try 40th Street and Jomax area, the stretch of desert leaves open area for play away from housing. You'll need to drive into it though to keep games safe and hidden. It isnt east valley, but it isnt in the aves either.

As long as it is South of Phx i am in!
How can we make sure that it is 'ok' to play there?

.. if this is a tiny field, and a generous amount of people are going. Why would you try to host a clusterf*ck game in a place that is considered to be a 'no-go, people might call the cops situation?' Count me out, it is nice to have a backyard field for you and some buddies to mess around on, but to 'host' a 'large game' on a so-so field that you "just cant lose" in opinion is stupid.   

Right, you see the intention was not at all to host a huge game in a tiny field! It was simply to get a few people out there to play a some games.
 
Given the response this thread had in the last few days, i received a few PM by locals that use that field, that brought to my attention these issues, and that we may run into some problems if (say) 100 people show up all at once!

As such, i thought i should make everyone aware of the situation (especially those that plan on driving from far away).
I have only been at that field ONCE, and it was not a "no-go", everything worked out fine!
As for the thread, I just happened to be the first that made a post about this. I am not "organizing an event" or anything!

So, be aware of the situation, that's all the information i have received so far, plan your weekend accordingly.

P.S. I think that it is not a good idea to use airsoft "guns" anywhere close to public streets or areas, regardless the size of the team or the place.
Most people don't know the difference (and don't even care to find out).
just my 2 cents..

I went to Fort Adobe with Jeff and Chris the other day (it was a Sunday about two weeks ago) and it was just the 3 of us!! and you have to pay the $20 regardless.
You should try Hatfield if you are North of Phx or Fuji Field is you are South of Phx. There are going to be PLENTY of people there and it is free!
my 2 cents ...

If everyone that says that they're coming actually shows up .. we'll have people everywhere!! 
You can just throw a BB into the air, and hit someone .. .. ..  the field is not that big !!!
