[pct-l] pct section hiker question

[Diana clare]

Cheers
I want to hike the PCT in the summer going northbound from the beginning of
the trail (san diego area) starting in June and go for about 4 or 5 weeks.
What challanges, issues, weather etc should I expect to encounter? I live
in blistering hot az so heat is a non issue. Also how many other hikers
would i see along the trail? any or none?

thanks
diana
