LOL, Spud, maybe...I hope my Puff(er) makes it into his 90's with me! I also agree with Skeptic, it would be very interesting to hear more from you, Spud.

Harold W., I don't know a lot about the oil shale reserves in Western Colorado, because I was so young and unaware when we lived there, but I do know my parents and a bunch of other oilfield people, pinned their hopes on them for a long time. I will ask my dad about them, now, but in the past whenever anyone has brought them up there has been general derision at the thought that it will ever happen. Frankly, that would just perpetuate the dependence on fossil fuels, anyway, wouldn't it? Geez, I hadn't thought of them in years; used to go tramping all over those hills...
