It appears many are seeing it as either wealth building, or fun and adventure. I'm here to tell you that you can have it both ways. Many of my fondest camping memories from my early years involve an old military surplus sleeping bag, visqueen plastic and clothesline to make a shelter out of and a coffee can for cooking with a handle made out of a coat hanger, and a very crude frame pack. Would spend weeks at a time backpacking with that setup. Later on added some simple climbing gear and checked out the Tetons from on top rather than just looking up in awe.
Via a military career, spent years living in and touring Europe, to include rail pass backpack trips in my younger years, Tip of Scotland to End of England bicycle camping, concerts, castles, bullfights in Spain, Kabobs in Greece, Octoberfests, medieval banquets, visiting every states and multiple countries, mountain tops for Mt Washington on the East coast To Whitney on the West, etc. etc.
Finally, having just turned 58 we are retiring to start Memorial day weekend, nice bank/investment balance thanks to living life within our means, a couple pensions, and the house and all the toys we owned outright. I totally agree with finding a way to do it now, don't wait. Having said that, there is a world of adventure to be had while still being smart and responsible when it comes to planning and saving for your future.
