Science Class
As I had expected, I am losing a little weight on this adventure because of all the activities we are doing.
However, the baggage scales at the Old West Train Station in Deadwood says just the opposite and that concerned me at first. Then I started mentally reviewing in my mind my old physics training.
As we all know, weight is determined by your mass in relation to the gravitational pull of large objects on us, like our earth or the moon.
For example, even though your mass does not change, you will weigh less on the moon than on earth due to the much smaller gravitation pull of the much smaller moon.

Since we have been traveling we have been moving further and further in to large, mountainous regions. Larger objects (Mountains) create a greater gravitational pull on another object and create the appearance of greater weight. (I need more research, but apparently this effects your appearance in photographs too).
Therefore I weigh less than the scales say.
Once I remembered this important scientific fact and applied the appropriate gravitational reducing scale factor to my current measured weight it turns out I am really only 205lbs, not 220+lbs like the stupid, luggage scale at the Old West Train Station said. Thus I have lost nearly 10 lbs in 2 weeks, not gained 5!
Weight * Mountainous gravitational scale factor = true weight.
220*.93=204.6
Whew! Science saves the day again!
