Two sources of transportation in and around the Yosemite:

Disregard all mention of Greyhound.They pulled out of area.

There is a bus from Lone Pine to Bishop:

It seems the best way from Whitney Portal to Lone Pine is to hitch. There are private shuttles. Average cost for the whole trip is $200.00. Here is link to Trail Head Shuttles such as Whitney Portal to Lone Pine: <a href"http://lomaprieta.sierraclub.org/pcs/info/shuttles.asp">Trail Head Shuttles
I am planning to just hitch all the way unless I come to my senses.
