That's pretty interesting!
In regards to dugouts, here's a few pics of my oldest son and myself paddling a dugout down the river where the Lewis and Clark
route was followed. We only did a 35 mile leg of the trip, it was done by several different crews.
It's not a memorable
boat trip unless a storm comes, right?
You can see the rain hitting the
water, it was raining pretty hard for a while so we pulled up under some trees on an island:
Sharing the river with the working crowd:
Anyway, sorry for the hijack. My last comment about primitive
navigation nowadays is it can be a pretty moot point when one realizes all you have to do is follow the contrails, a jet flying at 35K feet leaves a contrail visible from over 200 miles away.
