Jennifer,
I would ask, what to you want out of this hike?
When I was young I did two 6-month hikes. Basically started in the southern Sierras with no goal and destination in mind. Started hiking north. After 3 months I turned around and returned, not always taking the same trails back. I was alone most of the time, which I think was the best part. Those trips are in my mind. The memories cannot be lost or taken away from me. I cannot assign a value of any sort to them. They are there, big and and somewhat difficult to quantify.
I have thought about doing the PCT. The one thing that does not appeal to me is the social aspect, a time table to get to the end, and the constant re-supply along the trail to meet your time table. To me it sounds more like a job than an adventure.
When I was newly married (the first time) my wife and I did a 3 month, 10,000 mile motorcycle trip from Calif, to NY, through parts of Canada, and back. We towed a miniature tent trailer and it was a great trip. Different kind of trip, different goals. Different memories.
When I was 50 (and single again) I lived and worked from a tent trailer. Camped in all kinds of great places and worked a few days each week in locations around the southwest. Wonderful life and again had a great time. This was my nomadic stage of life. No great memories, just a sense of satisfaction of living in the work-world on my terms.
When I had kids, I didn't have the urge to do long hikes away from family. I still hiked a lot; but raising kids was job #1 and there was a lot of life satisfaction to this. I wouldn't change that period of time for anything. No regrets during this phase of life.
I have been married to my 2nd wife for 10 years. I am thinking about a possible PCT through hike. I think I may want to do one last big solo adventure. But I don't know that I want to be away from my wife for 6 months; and there is no way she would be willing to join me. The PCT would allow me to stay in frequent contact with her, but in my mind the frequent contact with her and others on the trail might diminish the "adventure" piece of the experience. It would not be as much fun as other adventures in the past. It would be a compromise for me.
I have made a lot of life-changing decisions; decisions that might impact career and even family relationships negatively. Once I have mentally determined "no regrets" no matter what the outcome; even if worst case scenario happens, I go for it.
Sounds like career, family or income are not an issue for you. That is good, because for many folks that is the overriding factor why they don't do something they dream about. So again, what do you want out of this trip? If it is something you just have to do; do it. If it is not a fire in your soul, reconsider.
