I like to see fields clean up once and awhile. Meaning: scrape off the load off splooge off the bunkers and rake up unbroken balls. I also like to see mudholes behind bunkers filled in with new, dry soil/straw or even mulch or gravel. Some well used bunkers get soupy quick.
I always like to see a ton of players, which means the field is doing something right by attracting the crowds. I also concur with the other opinions here on quick turnarounds for games. I don't like spending a ton of time waiting around. Decent field paint prices, and cheap entry fees cheap me coming back too.
