As for baseball, to the best of my recollection, I've been to 66, if I include 3 fields to watch high school games that normally have other tenants (Principal Park, Bucks Field in Waterloo, and Grandview College)
First let's start with the fields I recall playing on. Most of these school are consolidated, but I presume the fields are still there. Sanborn, Hartley, Primghar, Milford, Paullina, Sutherland, Alta, Aurelia from the Sioux Valley Conference. Not as many games played back then as now, so the non-con list isn't that big. Cherokee, Western Christian-Hull, Little Rock, George, Melvin, Storm Lake St. Mary, Everly, Ocheyedan, Arnolds Park, Sibley.
Next let's go with HS fields I have umpired on. Roland-Story, South Hamilton, Blairsburg NE Hamilton, South Hardin, Ames, Boone, Ogden, North Polk, Glidden-Ralston, Collins-CMB, Zearing Colo-Nesco, Dayton-SE Webster Grand, Gilbert, Des Moines Christian.
Then there are a bunch where I've watched Jerald play, either in school ball, or spring ball. Nevada, State Center-West Marshall, Marshalltown, Gilman-East Marshall, Waterloo Bucks, Ft Dodge Dodger Stadium, Ft Dodge St Edmond-Harlan Rogers Park, Jefferson Greene County, Prairie City-PCM, Carroll Stadium, Rippey East Greene, DM Roosevelt, DM East, DM Hoover, Johnston, Saydel, Ankeny, SE Polk, Newton, Waukee, Woodward-Granger, Bondurant-Farrar, Principal Park, Belmond-Klemme, Grandview, Van Meter, Mason City Newman, Martinsdale-St Marys.
Then I recall a few more, where I just went to watch for one reason or another, that didn't involve me, or Jerald. Floyd Valley in Alton, Granville Spalding, Sioux Center, Manson NW Webster, Slater-Ballard, Lawton-Bronson.
I don't know if I have a favorite. Probably Carroll Stadium, it just has a cool old time vibe to it. Not to be a homer, but I really like Norsemen Field. Coach Hill takes such nice care of it, and the grass baselines between home and 1st, and home and 3rd are a bit of an oddity.
My HS home field had its own oddity. Light poles in the field of play in right and center fields. They were there for football and in the way for baseball. I seem to recall you couldn't catch the ball off the poles, but you could the electric lines.
Martensdale-St Marys has I think an old brick bus barn as a home run "fence". As close to Camden Yards as you can get in Iowa I guess.
Back to my high school days, Ocheyedan didn't have a home run fence. Just a big open field. Run Forest, run! Lawton-Bronson has stadium seats, which is really cool for a small high school. SE Polk has the only all turf field of the bunch. Clean bounces, and clean jerseys.
Ames has a new field now, that I haven't been to. Their old field is kinda cool too. Lotta history there, including Satchel Paige pitching there. I'll leave with a photo of Jerald at bat there, back in 2015. I love the 4 legged light standards (and my cell tower in the background).
