I am a natural list maker and follower. Love "to do" lists, "travel" lists, "wish" lists, ect. That is why I am a natural peakbagger. I discovered a few years ago Peakbagger.com. This fabulous site has hiking lists from all over the world of various challenge levels. Some I know I'll never accomplish, like the 7 Summits of the World. Others I have a great start on. You can check out my list and maybe make one of your own.
For me the list is another way to get outdoors. I'm able to try new trails and perhaps challenge myself a bit more than if I were to hike the same tried and true trails over and over. This all started, for me, when I picked up The 4000-Footers of the White Mountains by Steven Smith. I never even knew there was such a hiking list. From then I was hooked. At the moment I have completed 50% of the AMC's White Mountain Four Thousand Footers List. I hope to complete a large chuck of it next summer and maybe complete it in the next 4 years. Meanwhile, because of Peakbagger.com, I've found so many other lists that are in the area. It's enough to keep me hiking and outdoors.
