I was confused with the map at first, thinking Mt Baldy Village (proper), but now I see WEST-siiiide.
A few things come to mind:
* The baldy area got some snow and sun in recent past weeks, but the temps are still cold at altitude. so the snow melt re-freezes into slippery ice.
* Bridge to Nowhere, haven't been there since 1997, but I don't think it changed much, you should expect stream crossing about 10x. This time of the year the stream is about waist high, running strong with pushing force, and freezing balls.
I would pad the mileage and time, 30+ miles is very conservative, those may be Topo map miles, but trail miles are more, and slower.
There's really no good place to camp along the Bridge to Nowhere, that trail is a zoo, which is why I stopped going there. The bungee jumping operation, the muchachos with hunting shotgun at the bottom, and teenagers leaving broken beer bottle glass everywhere. There's just no privacy with mass crowds on the weekend.
Best of luck to you, seems like an exciting adventure.
