It's always good to have benchmarks - data points you go back and look to for reference. I hope I do not refer back to this as the good ole days when gas was only $2.31/gallon.

Or do you ever pass a location that has been redeveloped and you try to remember what it looked like before? How quickly we forget something that we looked at everyday for months or years.

What other things should I be benchmarking - hum?
