The parent you're responding to specifically said 'disc' golf...which is a bit different than traditional golf --

1 - it's usually in parks (that are being maintained, but probably not watered...at least around here, I don't think any of our parks have an irrigation system...they are all just climate-appropriate land-/hard-scaping), or literally "in the woods"...the courses I've been on have been through nature trails, or sections of woods that were cleaned up (mostly of underbrush, saplings, and low branches).

2 - It's more fun to walk around and play stoned. In fact, I think that you have to be stoned to play in an actual league game. It's practically written into bylaws.

3 - Less professional socializing/networking. Mostly because everything about it is the antithesis of office culture.
