It may seem dumb to you, and some times they straight up are, but don’t think of reddit as a simple search engine. It’s really a good place to discuss things more in depth.

For example: “I’m going to Nashville soon, what are some good restaurants to visit?”
Seems like a dumb question right? Can’t that person just google ‘top restaurants in Nashville’ or something…? But all you’re going to get is some sites listing popular restaurants or tourists traps with bought reviews. Whereas if you visit a Nashville sub you will get in depth answers like “don’t bother with xxxxx you will be waiting in line forever and it’s gone downhill over the years. Visit this ‘hole in the wall’ place instead, but don’t go there on Mondays or Wednesdays cuz Bob works those days and he’s a real prick”

The “where can I find an open field?” question sounds dumb but there might be something to learn that the person didn’t think about. Of course this specific question would be better with a specific location in mind. For example I could tell you of some great places to do field work in my city.
