to give you some background i would put myself at level 2.5-done many trips, mostly in Yosemite-so almost all on trail, but am fairly comfortable going x-country.
i'm pretty comfortable in all conditions-addmittedly a bit uncomfortable with x-country simply because i don't really do it much.
main interests would be lakes, big mtn scenery, esp photography, spending time hiking by myself-and meeting people along the way and sharing tales.
for most trips i depart home-way down in Long Beach in the early AM, permit up and hit the trail-time off for me is limited so i do try to cram as much as possible in-while still finding plenty of time to enjoy the trip. i spend a lot of time pre planning, looking at topos to really get a feel for the trip to make sure i don't overdo it. i def get all comments about setting aside week long periods for these areas-of course that would be ideal, but due to time constraints i plan accordingly and see what i comfortably can in that time.
i'm solid with altitude, never been an issue-knock on wood right-and actually enjoy getting a bit worked on trips
your option C is on my list for later on in the season-definately want to check that out. thanks for the recommendation .
