Peter Vandorn, architect of Jackson capital in 1821, planned for a checkboard design of alternating park and city blocks, a plan first recommended by Thomas Jefferson. Smith Park is the sole remaining square from this plan that was largely not followed as Jackson grew. The park is named after Jackson resident and benefactor for the park, James Smith. Unfortunately, at the time of my visit, the park appeared to be poorly maintained.
Jackson is an interesting city. It has the potential to be spectacular, but doesn't make it. While there are many things that can be classified as good, there is also much that could stand improvement.
The city is not safe after dark. Although there are places it is safe to visit, I personally don't go into Jackson after dark. Jackson has a high crime rate, including car theft and murder.
There are so many other places in the country ( and even Mississippi) which offer the same things, and are much safer to visit.
