Let's dig into the mail bag, shall we?
Brian from La Grange asks...
I heard on a boat tour a while ago that there are some kind of sharks in Lake Michigan. Is this true?
Interesting question, Brian!
Short answer, no. Long answer, it's not impossible.
Sharks are salt-water creatures, and couldn't survive in the great lakes - the exception would be bull sharks, which can live in freshwater, and have occasionally been known to swim up the Mississippi River to the great lakes. In the 1955, there was even an attack - a boy named George Lawson swimming in the lake south of Chicago and ended up with a limb bitten off. We've no idea whatever became of George Lawson - he lost a limb, but gained a story no one will EVER believe.
So there's BEEN a shark in Lake Michigan on at least one occasion, half a century ago. It's unlikely that there are any of them now, but not NECESSARILY impossible. Sophisticated damming techniques make it harder and harder for them to get into the river nowadays, though.
Hence, you're probably pretty safe down at the Oak Street Beach this summer. BUT......There were also once reports of a sea monster in there - more info coming in the book!
