I hate to set you straight again but this is what I really said.
Ray, to be walking east on La Sombra to Buena Vista she would have had to have come down (south) El Rio from the direction of the park and La Loma. El Rio doesn't connect to Yosemite.
I didn't say anything was impossible. La Sombra is one block long between El Rio and Buena Vista. This is the only stretch of La Sombra she could have been on heading east to Buena Vista. All the other routes you came up with do not cover that route. And if any routes did go by Yosemite first,she would have to loop around and backtrack.
If you still maintain I said something was impossible, post it.
ya know, the difference tween mouth and motion....;-)
I know it quite well. It is something you should consider before going into your macho act.
