If it gets you from point A to point B and back again, that that's a good thing. You might be able to get 30 out of it. I get at least 40 out of my tercel but I hypermile. It isn't uncommon for me to shift to neutral, it's a manual, and shut the car off while I coast. Disclaimer: This is not recommended due to loss of power steering and power brakes. Not to mention this can be bad on some autos. I do not endorse this activity.
This is the face of a true hero that has paid sacrifices most will never understand. http://www.youtube.com/watch?v=0gfnmDGk0KM This shows you how difficult it is to stand at attention for four hours holding your salute. http://www.youtube.com/watch?v=lVT9TA9eA_I
I know on the Rolling Freedom ride we ended at QS&L and they had eggs, bacon, sausage then. Of course I think Casper got some wings too IIRC. Or maybe he was just trying the sauce...
What Shitty said too. You can actually use more energy to reheat it back up instead of not turning it down so low and letting it maintain. Most of the brands are pretty good, just don't get a $10 one. Expect probably $40 at least, although it's been awhile since I priced them. Like I said before, the best are the ones with 7 days and 4 time changes.
I have one. It's a touch screen, 7 day, morn, afternoon, eve and night. Get one like that so you have complete control. Some of them only have m-f and the weekend. My was a gift but you can get them about anywhere, Home Depot, Wal-Mart, Lowes....
