I know a lot of people like football fields, or soccer fields, or pretty much anywhere else you can go have a nice wide-open space to chuck discs. Where do you go, and why do you go there?
When I bought a house last summer, it was across the street from the elementary school (noticed that - kids will walk - nice! two playgrounds, nice!). I'm not sure if I noticed at the time, or absorbed the consequences, but I'm even closer to its big multi-purpose athletic field.
Throwing on the diagonal (which maybe has an elevation change of as much as ten feet, not too bad) the distance is maybe 350 feet or 375 feet downhill, with a nice parking lot for a tee pad. Maybe 325 uphill before you get to the parking lot. For me, for now, that's long enough. Hopefully some day I'll outgrow it for drives.
I putt in my front yard, where the city conveniently has a street light. Not huge elevation changes, but I can get maybe five feet by putting from the road. Sometimes I'll approach from the school fields across the street. Neither the fields or the street are very busy when I'm around (they get a certain number of after school athletic practices, but it's not too disruptive of my schedule).
I sometimes drag my basket across the street (Costco version of the InStep) to practice longer approaches.
What's it missing? Eventually, 400+ feet of length. And options for big uphills and downhills (but who has those?). It's also short on natural obstacles for practicing guarded drives, approaches, etc.
Otherwise, on the course, I practice mostly at Rogers Lakewood. Maybe two miles from my house.
I also appreciate practicing on courses with easier birdie chances, holes where it feels like I _should_ be scoring birdies instead of just working hard to maybe have a chance.
So, I sometimes play at nearby park-style courses (9 at Hawthorne, 18 at Purdue North Central) to work on that piece of my game (accurate drives, accurate mid-length shots, etc.).
