The original Gold Coast Dogs at State and Hubbard, 1989, Chicago. 

At one time GCD was THE hot dog stand in Chicago. The Potekin family sold off the chain in 2002 and most say it was never the same after.

Two photos taken from Lake Shore Drive at Belmont, looking south, 1951, Chicago.

Notice the three wide parallel lines that run along the drive. These were called “fins” and could be hydraulically raised or lowered depending on the time of day to regulate traffic patterns.

The first photo was taken between 6:30-9:30 am. One fin would be raised, creating 2 lanes of north bound traffic and 6 (!) lanes of south bound traffic.

The second photo was taken between 4 and 7 pm, showing 6 lanes designated as north bound (with three “express” lanes in the center) and 2 lanes as south bound.

During non-rush hour traffic, only one fin would be raised in the center, creating 4 north bound and 4 south bound lanes - the permanent configuration we have today.

I imagine this had the potential of creating chaos as the fins appeared or disappeared, but there are many mornings during my standstill commute downtown that I wish this was still in practice!

WGN’s Harry Volkman says it’s going to be hot and humid (the heavy snow and tornado are winks)…1967, Chicago.

Volkman served as meteorologist at several stations in Chicago, including WGN, WBBM (CBS 2), WMAQ (NBC 5) and most recently at WFLD (FOX 32), starting in 1959 until his retirement in 2004.

Volkman also happens to be the father of Eddie Volkman, half of WBBM’s Eddie and JoBo, who most now know from the United Auto Insurance TV ads.
