My story is a bit different…
Although I camped with my family as a small child, my first foray into heavyweight camping revolved around bicycling in the mid-80s, and I did that for many years. Of course, a light load on the bike was considered 40-45 lbs., and even though it was suggested even back then to keep the weight closer to 30 lbs., no one could see how. Traveling lighter didn't really come into play even though I had nearly wasted one knee and damaged the other. After six years and five big (over 10 days) trips, I "retired" from bicycle trips specifically and bicycling in general.
Back in those days backpacking was considered more work than play, and full of pain and discomfort (and proven true based on other posts here!), while bike touring was considered more civilized: you could go further and see more. "Credit card touring" was the ultimate, if you could afford it.
For some reason, I took an interest in backpacking in 1996, but failed to get anywhere. In 2002, after I read a lot about "go bags" after 9/11, I suddenly found myself researching sleeping bags and backpacks, albeit without the insight of lightweight traveling. In six months I had a 5.5 lb. backpack, a 2 lb. mattress, a 3 oz. baseplate compass–even a gnarly 1.5 lb. water filter. About the only jewel in the kit was my Marmot Hydrogen. A year later for a summer car camping trip I loaded everything–including my giant MSR bath towel, AA solar charger, silk tops and bottoms, fleece bag liner, and aluminum trekking poles–into my 4500 ci backpack, and found not everything fit! I did (barely!) manage to weigh it on the bathroom scale: 55 lbs.–ouch!
So here I am five years later, and most of that gear has been sold, given away, or is (mostly) languishing in the different corners of my home. Thanks to BPL and everyone here in the Forums, my 3 season baseweight is down to 18 lbs., and falling. My new quest is not necessarily to drop more weight, but–like others here on BPL–to reduce the fiddle-factor: reducing complexity and amount of equipment taken on trips.
