Ok,so finding a location in orlando is not as easy as it sounds.
I'm not to familiar with the area,and the fue places I was able to find are just parking lots >.<
BUT!! I do have one idea.
What about my place? I didn't mention it before because I didn't want to be unfair with drive time.
But I have over half a city block and I can fit over 30 cars. I can supply music,chairs,tables,bathroom,water hose for washing, It's fully shaded by the trees. AND I can supply some food and if you want I can arrange for a food vendor.
It's in historic Downtown Brooksville"you can see the courthouse from my front yard"
It's just a thought and I wouldent mind doing it at all.
Let me know what you guys think.
