"I stopped at an Iowa Welcome Center on Interstate 35W..." Steve, now I know you're lying. Every good Minnesotan knows there is no 35W in Iowa, just the Twin Cities. :o)

Besides which, I-35, being odd-numbered, would be a N-S highway.

"Besides which, I-35, being odd-numbered, would be a N-S highway."

While it does go N/S, 35 spilts into two highways just south of the Twin Cities, basically one thru Minneapolis (35W) and one thru St. Paul (35E). It combines again on the north side on its way to Duluth. I was just poking fun with Steve.
