Ack! A bear? So, what campground were you in? Were there a lot of bear sightings? 
Upper Yosemite Falls.  Hmm.  I think that one is too hard for me.  Is that on a lot of rock, with narrow trails?  
The rafting being mellow is just fine with me.  A nice little workout, being in the water with my two favorite allies, I hate for it to end.  Unless it is too sunny, eh?  Then it is just float and burn.
