I did a quick 6 mile hike today with the new trekking poles. I left the poles against a tree to do some off trail exploring, when I returned I had a hard time finding them. When I got home I used some orange paint and foil tape to make the poles a bit easier to see.
When I made the poles I used a chrome plated butt cap at the top of the handle. It didnt take much time in the bright sun for me to realize that this was a bad idea. Hot metal, burnt thumbs! I replaced the butt caps with corks that I had in the shop.
