[8] The post office was established January 11, 1887,[8] with its first postmaster being Andrew Ennis, Sr.[9][10] It operated out of the railroad depot on the Lisbon side of Colgate.

[7] A cross-street on this side was named Wagner Street in his honor, which is now called Short Road.

[7] The night of October 16, 1901, two Chicago-bound freight trains collided on the Wisconsin Central Railway tracks between Colgate and Rugby Junction.

[7] The post office/general store was rebuilt December 15, 1903,[8][18] this time on the northern (Washington County) side of the road.

[21] The occasion resulted in the biggest parade the community has ever had, consisting of 89 vehicles proceeding what was then still called Main Street (now County Line Road/County Road Q).

[22][23] Forty firefighters from surrounding communities responded, and Robert Pickhard from the Richfield Volunteer Fire Company lost his life battling the blaze.

[25][26] In 1983 turkeys were rare enough in the area that when a friendly hen adopted downtown Colgate as her home, it made news.

[8][27] Postmaster Burton witnessed the bird's death from a hit and run collision in November of that year.

[5] In November 1987, the former Stirn General Store and Post Office caught fire after standing for 84 years.
