I need to plant something on 2 acres that's green and soft and doesn't require a lot of mowing or watering.

... because it's my field for paraglider landings, model rocket launches, and power wheels/ one wheel with my kid. Won't get a ton of foot traffic, nd it doesn't have to look great. -Zone 7a ,Central PA -Don't have a great well to provide water - I won't be around from June1st -September. So mowing will be expensive to hire out and grazing animals impossible to care for. - I say Dutch clover and get laughs. -ive heard Bermuda grass, but water and mowing? -I've heard blue fescue, is this good? - I'm a noob.

Any good seed blends to recommend? How should I get it started?

Thanks for whatever you can teach me!
