Not rude - just frank.
It's nearly impossible to do SFO-SEA-DEN in four weeks.
(Unless you are a racing cyclist on steroids)
Not to mention the issue of riding north on the PCH.

I've come to the assistance of cyclists, hikers, skiers, and drivers who were in over their heads.
I don't mind doing so - but most were seriously unprepared or unaware.

Since you are from Arizona - I've carried two packs up from the bottom of the Grand Canyon -
When a person had overestimated his abilities AND overloaded his backpack.
(Somebody I had never seen before but was ready to keel over)
Almost always these people are from back East or from Europe.

Based on the info given by the OP -
Do YOU think he/she is aware of conditions in the West??
