Have you ever biked around the Natchez Trace, it's something like 450 miles long.
no, sounds like a great adventure indeed, where is Natchez Trace located?
I believe its Northeast Mississippi and Alabama! 
ok interesting, I like to stop and take photos while I bike through nature, do you know a good nature trail?
I'm up in the PNW so all the trails I know are half the U.S. away, haha. However , if you do find yourself here Pullman and Klickitat are equally beautiful trails. 
nice to know I will have to check those out, I am in Memphis, any good biking areas in Memphis?
I've never been there but a quick search shows that Shelby Farm Parks is a nice are witha trail. 
Shelby Farm Parks will be my next trip, what should I bring for my bike trip?
I'd assume water, snacks and a first aid kit maybe a light sweater as well!
those are great suggestions, do you know what I can do about low tire pressure on my bike?
