FWIW I am of the same age and locale and mindset of DW and I can guarentee that he has no old blankets left over from the 70's. LOL If he is like most men of that age he has fond rememberances of the era, but has no desire to remember. Hell, I bet that he even had a lilac jumpsuit, but you will never get him to admit it. (I plead the 5th)
LOL
Remember "leisure suits"?!
