I have not lived on AC but I have spent several years overseas. There were things I missed.
Beef. Big thick red slabs of Oklahoma beef. I miss that anytime I'm away. Except in Argentina.
My family. They are the only reason I"m still here.
Space. Big houses, big yards, big cars. I own a ranch. I like the space.
Shopping. Real shopping. Big mall shopping. "Honey I just paid off the VISA" shopping.
American hospitals. They really are the best in the world.
