The 60,000 rounds per year Max mentions equates over 365 days to 164 players per day, ie 328 feet walking on some part of the playing surfaces or transition areas. Pondering this in terms of the same number of people walking across my lawn/back yard mown grass and the impact it would have on the quality of my lawn.
Pace of play, as mentioned by Tim M, is an interesting aspect too. Slow play ain't imo much fun. The closeness of tee-time intervals might have an impact here.
