I bring along a small travel bottle of solution and a pair of glasses as a back-up. It's just second nature to me since I'm blind as a bat without them.
I don't think there is a cure for this sickness. I just got the bug again recently and I am averaging 20 miles a week and feeling better than I have in years. HAZ is a great tool in helping me with my reborn passion and I wanted to say thanks to Teva for doing such a great job. See you on the trail.
Hiking alone can definitely be a great experience, but for the most part I have someone with me. You just never know what can happen out there, I guess that's what makes it so enjoyable.
