Well, I live about 3 miles away from Cedar Point. I can see it across the Sandusky Bay from my home in Marblehead, OH (tiny peninsula in the North part of Ohio). However, because I am surrounded by water on three sides, to get to CP I have to go around the long way, so to get to a place that's 3 miles away takes about a 30 minute drive. I guess I can't complain.
Other than that, SFO is one hour and forty minutes away, Kennywood is 3 hours away, and PKI is about 3 and a half.
