You can find Altimeter watches at some of the
better sporting good stores. Also, some of the new GPS's have a built in
altimeter. The Garmin 60 CS is one of them. We had an altimeter watch years and
years ago, long before all the newer GPS's and such, and really liked it as a
training tool for conditioning in the mountains. It was fun to see what the
elevation changes were where we rode and often went camping.

elevation changes to justify an altimeter)
