Hello Mike,
Many years ago, I hiked the majority of the PCT. It was an awesome experience. I remember that I thought about food a lot!
One thing to keep in mind is that it is a Crest trail, and that means that most of the time your water source is below you. So, you are hiking ridges and crests and your creeks and lakes are below. Generally, that means in the evening you hike down to the water source and start your morning hiking back up to the ridge and crest trail.
In some places you have to cache water before you go, probably not in your situation.
Make sure you have bail out points in case of illness or if your boots or stove decide to die. Or if bears eat your pack :shakin:
Hiking around Crater Lake is a lot of hiking in the trees, but once you get to the Cascades--man, what views! And views to exclaim over in the High Sierra's! The hardest part is through the Mohave.
Sounds like a super trip for you!!
