I returned from the conference on Friday, 1/27. On the return, I confirmed that it was Goat Gap, not Goat Cap. Another interesting sign was the Hound Dawg Holler Flea Market north of Clinton, AR.
Little Rock's River Market area has some attractions, but is mostly bar/restaurants of all types. Just to the west of it is the Old State Capitol museum; to the east is the President Clinton library. I did take a short tour of the Library at a Wednesday evening function; it's mostly an exaltation of his presidency, which I guess one should expect. I couldn't believe the extravagance of the gifts from foreign potentates (these belong to the US, not to any president). Guess I'll have to go back to the Truman Library for a comparison.
The return trip was 337 miles, 36 on Thursday and 301 from Conway to home. Best gas prices I saw in Arkansas were at Clinton, about $3.19 (in Warrensburg, it was $2.99; many AR places were $3.39). Smith's Restaurant in Collins still has great food - but bring cash.
