Good for you, I am doing want I can but unfortunately I live between Houston and Galveston, off the beaten trail but entirely to close to the Mega City. But I do have a working water well, a nice large garden, plenty of caned goods, wood stove for cooking etc. And best of all Galveston Bay is my front yard so sea food will be on my menu should things go south. My only real worry is tons of friends that are doing nothing and Houston, 30 miles up the road. Every time I go shopping I’ll spend 20 or 30 bucks on stuff I think I might need. Been going that for 2 or 3 years so I am in good shape as long as city folk don’t find me. But I much rather have a farm in the country like you do, that is very cool.
I lived in Houston for eight years and believe me, the zombies will find you. You might want to consider NE Texas or even Arkansas.
