TL;DR: Old Amoco sign and a patch of overgrowth hiding broken gas signs and stuff.
History: Following the Standard Oil breakup in 1911, Standard Oil of Indiana took over services in the midwestern states; later absorbing the American Oil Company. By the 1970s, Amoco became the company’s primary brand, and in 1985 the company itself was renamed the Amoco Corporation. “Torch & Oval” signs dotted the American roadside en masse until the company merged with British Petroleum in 1998, and the newly-formed BP finally rebranded all Amoco stations to its namesake starting in 2002.
The Wauconda Amoco station near Routes 12 and 176 was torn down years ago and replaced by a modern BP, though its original Amoco sign continued greeting those coming off southbound Route 12 for several years.
Explore: The Amoco logo was a familiar sign from childhood so I was happy to find this on my route to work when I changed jobs a couple of years ago. It was certainly the last one in Lake County (prior to then, the last one I knew of was removed in 2008), and probably the Chicago area as a whole, as by this point the brand had not existed for more than a decade.
A 2012 storm blew-out the side facing 12, and it remained blank for about a year. On a whim I happened to catch a blip of red and blue buried in the overgrowth, so I stopped and poked around – finding the shattered remnants of an Amoco oval, and strangely a broken ARCO sign; now another BP-owned brand which has not existed in these parts since the mid-80s. Also tucked away in the dirt and overgrowth were pieces of another indistinguishable sign, and the chassis to a car that had rusted beyond identification.
In a couple of strange moves: they first flipped the Amoco sign facing 176 to the 12-side and installed a blank-white cap in its place in the spring of 2013; then about a year later started clearing all of the overgrowth and crap surrounding it. Fearing it, too was about to come down: I shot a couple of long-exposures at night, using an el-cheapo flashlight to “light the sign” one final time. Today the pole remains, but an ugly BP “Helios” caps it.
