New Rzr owner needs tips

Hi everyone,
New to the off road thing. Did a half day in an unlimited buggy in Reno and was hooked. I was shopping for a utility UTV for my wife to use at our place, saw the Rzr desert edition and was hooked. So, ive ripped around our property some, dumped it on its side once and I’m really enjoying it. I do have a couple questions though and was hoping someone here would know.

Where are some places around San Antonio Texas where I can really run this thing?
Where can I find some window nets so I don’t break an arm when and if I flip it again?
Also looking for a couple fire extinguishers and mirrors.

Looking forward to more fun in this new adventure!
