Well, here we had trouble finding 3.0 singles players, and it didn't get better at 3.5. And the horrendous 3 hour pusher game I refer to, I was playing 3.5, against a young lady that had just dropped from 4.0. (And no, she wasn't the one pushing.) In NorCal there are so many players that the areas are pretty small. And if you are willing to drive, say 20 minutes you can play at the same level on three different teams each season. So the singles players often play on multiple teams.
