Walking Sticks

Do you own or use a walking/hiking stick? I personally do not use one, but I've seen some really cool personalized ones while working as a ranger. I love seeing what people add to the handle of their sticks; things like special beads and feathers. I also love seeing the hiking medallions people have collected. If I used a hiking stick I think that would be a goal of mine- to collect as many medallions as I can. What would you include on a homemade walking stick?
