Also, Sweet said that a bicycle is an unworkable transportation solution where he lives. Do you think that's the case?
Unworkable? No. A bad idea for a long term solution? Absolutely, unless you're set up somewhere very close to wherever you need to go.
Jonesboro itself is a smallish town but it does sprawl some, in that if you live at one end of town and need to go to the other it's several miles and there generally aren't bike lanes or anything to convenience bikers (this may have changed in the 10 or so years since I've been there, but, if it did it would only be in the area on or immediately surrounding campus).
If you live outside of town in any capacity, even in many of the more suburban neighborhoods, then it would be many miles one way to go anywhere, and you'd be surrounded by nothing but fields and rural highways for a good 50 to 100 miles in most directions. There's a WalMart, a mall, a bunch of hotels, a bunch of restaurants, and that's it. The nicer downtown area with the art scene etc is about two blocks in any direction in size. All of this is within a mile of the campus. Live anywhere outside that mile diameter and you're probably going to be miserable without a car. He might could have made do with a small scooter or something, but I doubt he'd be courageous enough to dare.
For what it's worth, tho, I live on the West coast now in a very "bike-friendly" area, and no one here does the no-car thing except obviously homeless people or those with DUI's, so, pretty much anywhere in the US that I can tell, outside of major metropolitan areas, are going to be pretty much unworkable without a vehicle if you have a job.
If you're a duck hunter, a fisherman, or similar outdoorsy type, Arkansas really is kind of a paradise, albeit a swampy one.. But if your idea of fun is clubbing or even just hanging out, it can be a pretty repressive, religious place with outdated laws and an unwelcoming atmosphere for people who act strangely. Keep in mind, in the 1980s it was still so backwards there that a white woman being with a black man would be met with open hostility in public. The 90s weren't very far off, and it's very likely Sweet was raised by or at least around some very hardcore ignorance to the point that it would seem to be the norm.
