Ask MetaFilter is one of my favorite web sites (I read it daily). In between various RelationshipFilter threads you can sometimes find gems like this:

Twin Cities Turtle-spotting spots
"My wife loves Turtles. Can anyone tell me where best to go, in the Twin Cities area, to see turtles in their natural habitat?

We're looking for (Twin Cities, Minnesota, USA) metro area parks, rivers, lakes, etc.; where we have a good chance of spotting wild turtles basking. While we're on the topic, any tips about the times of day or of year that are most favorable for spotting turtles will also be most welcome."

Several good answers follow.
