I love the scene with the crazy rednecks shopping in the "survivalist" store ranting about Commies. The grandmother with the shopping cart of grenades is fantastic.
The episode is amusing and clever. It's got a good movie reference to Hitchcock's Suspicion (? I think). Laura & Remington's relationship is progressing nicely. I'm still not in love with Doris Robert's slavish devotion to Remington, but I remember liking her by the end of the series, so I"m sure I'll get used to her again.
Keep an eye for Jane K. from Malcom in the Middle as one of the wives.
PPS. I have that same dictionary Laura uses at the end and now it cracks me up when I use it.
