Walk to my work? Are you kidding me? It's 15 miles to work and 15 miles back home. That's like 30 miles a day. Walk 30 miles a day? It will take average 1 hour to walk 3 miles, 5 hours to reach office and 5 hours to come back home. That's 10 hours, 8 hours of sleep (may be more than that since you are tired of walking so many miles). It's better to pay for the gas than move closer to office. So, let's not walk. What happened to those ideas that keeps on poppin' up once in a while when they run a vehicle with water, less oil and stuffs? I have heard so much about them but never really seen those ideas making any progress.
