I don't know what's going on, but the speed limits around Cleveland, OH need to be increased.
There are dozens of streets that are marked 25mph that should be 30, and the highways are marked 60 need to be 65.
The turnpike is 65, and should be 75.
I am not sure why they are so low. All I can think of is revenue generation.

Where they talk about expecting more traffic tickets in a weak economy. I know I've been seeing more cops lately. Gotta make that money!
