And this brings me face to face with an inconsistency.
Most of us here keep track of the peaks we have hiked to the top of and we check them off against a list that was established by someone other than ourselves. Correct?
So, if the actual experience is the most important element of peakbagging then keeping track of our progress against a list that was created by someone else totally negates that and suggests that we hike these peaks in order to compare ourselves to a bunch of strangers.
If I may jump in with some random comments as I have thought about this question often:
1. Everyone who hikes gets his or her ideas for destinations somewhere...a guidebook of some sort, a website, hiker friends, or maybe peakbagging lists. For those obsessed with mountains, whether peakbagger or not, "the lists" are a good place to start, so peakbagging to me is a nice way to get a broad view of the mountains, not always gems, some easy, some hard, the outstanding ones, etc....
2. The word "Peakbagger" means different things to different people. A personal example: when I completed the W48, it was on West Bond. I had done Bond and B.Cliff 6 years prior. I wanted to do an overnight for this one as I had for some others - so it took me 4 more attempts with a backpack before the stars aligned. I could have found easier, lighter, faster, and quite frankly warmer options for "checking it off." We all hike and experience the lists differently. TEHO, HYOH, etc. If blazing through the lists makes one happy, then hell yeah, but even among peakbaggers, we're each unique in our methods/experiences.
3. The experience is different for each "peakbagger" regardless of whether one is hiking a list someone else created and did first...there is always someone who "did it first" on some level - these mountains have all been climbed, named, and mapped. Your experiences hiking a list is a combination of many factors, only one of those being that someone did this group of mountains before. If you believe in impermanence (I do), the trail, you and everything else is in a constant state of change anyway - it's different every time.
4. Let's say I come up with the next great peakbagging list and I'm the first to do it. Have I done something new? On one level yes. On another, no - people before me have been coming up with lists of mountains to climb based on a set of characteristics for years. It's not a new idea, just a new spin off an old one. You can focus in or pull back your perspective a little when looking at this.
I come to the same thought most times when thinking about the more existential issues that accompany peakbagging. To me, the more essential question is not if one is a peakbagger, but rather whether or not one's soul is connected to the mountains.
Just random comments, all my opinion.
