So, here they are, in no particular order.
1. Bells Bend Park. This is my "home" park, so to speak, the one I go to every chance I get. They've mowed some of the big meadows and I ended up in a field I'd never seen before just this weekend. It was beautiful. I've promised many people that I'd continue to tell you that the park sucks, so that it won't become crowded. So, let me warn you that the park is full of feral babies that bite and shoot lasers out of their eyes. Proceed at your own risk.
2. The Public Square. There's public art, beautiful architecture, water features, a history timeline, and plenty of interpretive signage. It would be physically impossible for me not to love this park.
3. Fort Negley. This is one of the most special spots in Nashville. It's at the top of the hill that the City Cemetery (another wonderful spot) sits at the bottom of. If you haven't spent an afternoon there, you're missing out.
4. Lock Two Park. If you only went to see the benches that look like Stonehenge, it'd be worth it. Great views of the river, great playground equipment, a mysterious old building, and the chance to attend Narc Day, whatever that is. If it had historical signage, it might be Nashville's perfect park.
5. Lock One Park. As I said, this park is Nashville's creepy basement, where you go to find the ruins of centuries of Nashville history. Here was a buffalo ford, a small fort, a lumber operation, and a great place to fish or see downtown. If you go, be sure to go with someone, because it's not really safe. But do go.
Okay, one last thing before I'm finished. I just want to say thanks to y'all for your awesome comments. I am really thankful that I could always count on you guys to know the answers to things and to have good tips for me. You made an enjoyable project even more awesome.
