Sure
 

But you are in the big city. I am further south and much more rural.

In Alabama its 3 man varsity, 2 man sub varsity. It might be two man for varsity out where you can hear the banjo music, but we try not to go out that far.

In Our Little Corner of the World
 

In this part of Michigan, all varsity seems to be 3-man. For most big schools, JV is 3 man. For the smaller schools, a single JV game would likely be 2 man. If it's a frosh/JV doubleheader, it will be the same 3-man crew doing both.
Got a non-conference 2-man frosh/JV doubleheader, which is a rarity, next week. That's a lot of running, but the pay is split between two officials instead of three, so that sorta makes it worth the hoof-pounding.

When I was in Des Moines, virtually all Frosh games were double headers (2 man). I was a little surprised to find they were all singles when I moved to Colorado.

Illinois uses 3 Person for all post season games Boy's and Girl's basketball.

I have heard rumors of some places using 2 Person still, but it is not very common. Every league or tournament I have worked is 3 Person for all varsity games.

There are even places that go 3 Person for lower level games. This is not common, but it has taken place.

General rule in Texas is 3-person for 3A, 4A, and 5A games (three largest classes which make up most cities), 2-person for smaller schools and almost all sub-varsity.

Yoncalla?

TN has geographical differences. "Greater" Memphis, Nashville, Knoxville areas all use 3 person for varsity, 2 person for sub-varsity. The "in between" areas still have many schools that use 2 person for varsity.

For the most part, most schools hire three officials for varsity games. There are a few exceptions that only hire 2 officials.

In my neck of the woods, we do 3 person all season with the exception of AAA Girls Varsity, Private Schools and JV. All post season is 3 person.

Same in NM which is where I just left. In AZ, all 2 except for post season (not sure of which post season as this is my first here).

Out of curiosity, in places where varsity is 3 and sub-varsity is 2, how much are the game fees for each?

____________________

A few places still hire 2 for girls V or 3 for a JV/V combo. I've heard of places where boys still have two for V but haven't seen it for years!

Kansas uses 3 whistle for Varsity, 2 for sub-varsity.
