We don't need no stinkin' field!
Where there's a will, there's a way, bro!
Just remember summer's about 1/2 over for you and the days are getting shorter. Aren't there a few desolate roadways or business parks, etc., with 2-4 lane roadways that aren't used much on weekends where you could fly with a spotter? My brother-in-law and I occasionally fly on Highway 36 in Eastern Colorado when I'm visiting. On weekends the traffic can be as low as one car every 20 minutes.
I agree with woketman. Keep the accessories and whiz bang stuff to a minimum until you learn the airframe, then add stuff to it later as you desire.
