And now you know

Did you ever wonder why Hawaii has an interstate?
I did too. What state are they connected to?
Well I learned that President Eisenhower borrowed the idea from the Germans, who use it to connect military bases, not states, like we think. And since Honolulu has 13 bases, they have H1, H2, and H3 to connect them. But don't go any further. You'll run into H-2-0.
Okay Alex, I'll take random worthless facts for $400.
