I remember an article about Eureka Springs. It sounds like a really interesting area. I still haven't been to Arkansas or Oklahoma.
Eureka Springs is beautiful It is like Manitou Springs south. The history and legends of Eureka Springs and Manitou Springs are virtually identical. Both communities are very unique and artsy and the style of architecture is predomonantly Victorian. Both have very quaint and lovely historic areas and the streets are narrow and full of twists and turns because the homes are built into the sides of mountains and hills. Both have very cool shops that sell stuff you won't likely find other places, particularly Eureka Springs, and Eureka Springs has a tremendous diversity of exceptionally good food, and you can get a good barbecue there. I would not recommend ever ordering anything off the menu in Manitou Springs that has the word "barbecue" in it, however, Manitou is hard to beat for buffalo and elk meat and Mexican food. Both towns have caves nearby. In Manitou the predominant style of music is native American whereas in Eureka Springs it is more country and bluegrass. Both towns are rich in history and are incredibly photogenic.
