I like tents. Nemo, BD and MSR are brands I like.
I really like that when I'm zipped up in my tent I don't have to deal with bugs, which get quite annoying if you're hanging out at alpine lakes here. This is actually where I do most of my camping.
Also, because it is the PNW rain is something of an issue. Not heavy rain but usually sprinkly annoying middle of the night rain. This is actually the reason I switched from a double wall tent to a single wall tent. I had a double wall and I still had to use the fly. This negates the "moon roof" feature of mesh tents up here such as the Hubba.
Furthermore, I tend to go up with my dog, I think his den/crate instincts kick in when he goes in to the tent. He sleeps better, isn't on guard and we both get much better rest.
Lastly, I grew up being coached that you train the same way you compete. So, I use my weekend camping trips as training for longer trips. For example if you look at my gear list I bring those things with me at ALL times. I add other stuff depending on weather, length of trip etc. Typically, for me the difference between an over night and a two week long trip is a few pairs of extra socks and a few pounds of food.
I'm not a true UL packer I'm here to learn. I definitely don't mind having 3-5 extra lbs with me because they're usually in the form of booze, wine, cigars etc.
What I do love about my system is that I'm comfortable with it for the short trips (ok super comfy) and by the time most people gear up for a two week trip they're carrying as much weight as I am if not more. The difference at that point is my body is used to the weight.
