Kid,
I think the arm chair+ quarry divers are jerking your chain, Do you have a dry suit or cold water exposure gear and cold water regs ? is the question that should be asked.
Diving around Chicago
There are charter boats available see list lower page, and renting equipment is generally procured through the charter boat companies but ask.
you can explore a multitude of shipwrecks on Lake Michigan. Most wrecks that occurred in the early part of the 20th Century have been destroyed by the local government for being navigational hazards for other nautical vehicles. However there are a few left worth exploring, most easily reachable by charter boats:
The Sebastopol was a steamer that went down during a gale in 1856.
The David Dows was a cargo five-masted schooner that sank in 1892.
The famed passenger liner, the Iowa, became stuck in ice and sank in 1915.
The Tacoma was a wooden steam powered tug boat that sank in 1929.
Evanston Beach, north of downtown Chicago, is home to the wreck of the George Morley. This wood hull freighter sank 1892 off the Chicago coast of Lake Michigan.
