Week? Day? Challenge 6, I think

Just wanted to tell you guys that I've still been eating well, except for last night I had a bowl of lf reduced sugar ice cream and last week missed 1 day of exercise(unloaded 6000 lbs of rock for a new rock garden) but everything else is still on plan.
I have been on a fact finding mission. I have discovered that it is possible to run my diesel truck on waste vegetable oil(wvo). That's the oil they dump into sumps from the friers at the fast food joints. I still have some more research to do and might set up a little experiment using my tractor, but I think this is a totally doable thing. The other option I have discovered is home brew biodiesel, using wvo still but adding chemicals and cooking it to make the fuel. Methanol and heat, yeah that's a good combo,lol. Anyway I'll keep you guys posted on the wvo and hope to have made some in the next week or two. You think when I fire up the truck on it, it will smell like french fries, lol. I guess we'll see then if I can get over that food craving!
