If it was two gallons of gas, it would cost about $7.00 today in Denver, CO.

In my case, the two gallons is the total amount of blood I’ve donated so far. The value of my two gallons is likely quite a bit north of $7.00 to those in need.

If you aren’t a blood donor, you can be. If you really have a phobia about needles (like I had), giving blood will help you get over that phobia. I don’t get weak in the knees anymore at the sight of a needle, (but I don’t watch them put it in either).  🙂
