Ok so the current Minnesota Department of Transportation Bicycle Maps seriously suck. They were designed in 2001 and have been untouched since then.
The good news is that they are trying to make it better. Right now you have an opportunity to help out by filling out an online survey. I know, I know the flier says the input is due by January 1, 2011, but they survey is still available and more input is better so hurry over.
There are tons of maps available online, but one unifying map for the state could definitely be useful, so come on, it only takes a few minutes.
