Hi everyone. I have been slowly accumulating gear but the one big piece I don't have is a shelter. I just went (car) camping this past weekend and I had a blast. I slept in my friend's REI Half-Dome 2 person tent from early 2000 and it worked great. It was a big crowded with her dog inside but it was perfectly fine. I am 5'8" and there seemed to have been at least 20" of spare room length wise. As long as it's roughly the size of the Half-Dome, I don't need it to be much more spacious.
I don't think I ever intend to hike solo so being ultralight is not a huge concern. I am packing pretty lightweight though and I do intend to do backpacking, so not just car camping where weight is not a concern. I'd actually like a solo tent but to be honest, I don't see a situation where I'd go solo. I just hate the idea of being in a situation where I am sleeping alone and have to deal with the weight of a 2 person tent.
Anyway, I live on the Central Coast of California. The coldest it got this winter is probably low to mid 30's. I am not planning on camping in Alaska or anything.
I am looking for a lightweight (4 pounds or less, preferbly) 2 person tent that can comfortably fit two people. I want a real tent, not a tarp or anything requiring some funky setup like the use of trekking poles. I'd like it to be free standing. I am looking to spend $300 or less if possible.
P.S. I did see other threads with similar requests but I didn't want to intrude on their topic.
Thanks for your help.
