A new alternative fuel?

Yesterday we pumped up our bicycle wheels and took advantage of the glorious spring weather by riding to the Chicago Botanic Gardens. At the garden I ate a bowl of oatmeal with milk, butter and sugar - cost $1.50 for about an 8 oz serving. Our total riding distance was about 11 miles. So, we got about 11 miles per bowl, which is equivalent to 176 miles per gallon of oatmeal.
This sounds great on the surface - but a gallon of oatmeal would cost $24.00.
A better measure would be cost per mile - the result is:
Oatmeal+Bicycle: $0.136
Gas +Automobile: $0.143
This is a wash - but oatmeal has less impact on the environment, so it wins overall.
