Where the I Divides
A sign outside of Tomah proclaims it to be "Where The I Divides," meaning that it happens to be where Interstates 90 and 94 split, one to go west toward La Crosse and Rochester, the other to go north to happening Eau Claire. It's a feeble claim, made worthy only because the town decided to put up the sign. This is at least preferable to the town's only other claim to fame, that it's the birthplace of cartoonist Frank King, creator of "Gasoline Alley," a comic strip so old that even we have difficulty remembering it.
The band Information Society, which hailed from Minneapolis (slightly further up I-94 from Eau Claire), wrote a song in 1992, "Where The I Divides," inspired by Tomah's sign.
