18 cylinders:
2 cages=14 (8+6)
bike=2
self-propelled push mower=1
weed trimmer=1
The car can carry up to 5 passengers (typically 1-2) avg. 25 mpg , SUV 8 (typically 1-3) avg. 15 mpg, and bike 2 (more likely 1 for now) avg. 40 mpg. Also have a 8 cylinder classic car getting restored but it is not on the road, stripped down to nothing right now.
I average 40 miles round trip commuting to work 5 days a week, wife the same with seasonal work. I use the car most of the time but hope to use the bike more when the weather & roads are okay for riding.
I recycle at all times what I can, when I can, especially at home to keep my garbage minimal. I'm conscious about any form of littering & impact to nature anywhere I go.
I think tree huggers need to let go so we all can enjoy the forest. Anyone who spikes a tree should get the death penalty, I have lots of logging friends that farm selected forests legally & in consideration of the environment, they are not the reason for global warming or the elimination of old growth or possible extinction of the spotted owl. They should direct concern to the government & corporations controlling our national & state forests or invest in property & grow their own private forest, but then that takes a lot more work than hugging a tree and playing protester anarchy.
That's my slant on carbon footprint, eventually we all leave the same amount when we are buried 6 feet under, my wife & I want to be cremated then...
