The T-128 in Lake Mills is on Cherokee Path, near some condos by the Interstate. The old P-1x was by the school near there on Pine St. I think. Tempest must have replaced it.
One of Waterloos' 2001s is next to the water tower.
The P-1xs I know of in Watertown are/were mounted on the supports of the water tower on O'Connell St., the parking lot of Schurz Elementary along Clark St., and by the water tower on Western Ave. near Concord Ave. You might look at some of the subdivisions around the periphery in parks for newer units.
Fort Atkinson has
a P-1x along Jefferson St. in Ralph Park. It's pretty low mounted! Their 2001 is atop the Municipal Building on W. Water St. at N. Main.
