I got the four movie DVD, "attack pack", at Wally for about $12. I watch movies when I exercise at hope. The Tremors movies are just about the right sort of movies for this. Lively, funny with a simple plot and clear action. Not too much deep thought needed.

The Tremors movies are something of a touchstone within the survivalist and preparers community. If you mention that someone is a "Bert" everyone knows what your saying. He is something of an archetype.
