We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
The interstate system was constructed in the 50s with funding coming from the National Interstate and Defense Highways Act of 1956.
My understanding is that it was built (among other reasons) for military purposes (ferrying troops and supplies). I believe that the interstates have the requirement that 1 mile out of every 5 miles has to be perfectly straight, to serve as a temporary landing strip for military jets.
