Yosemite is one of our favorite places.  We went in October 1997 and again in October 1998.
The pictures below are from the 1998 trip, when we spent an entire day hiking to and from the top of Halfdome.

One of the many views from Glacier Point (Halfdome in the background).

Haley, with Halfdome in the background.

 
Many hours after we started, we are near the top. 

Marc on the ropes; it is rather steep.  

We made it!  

We hang for a day with friends Cathy & Chris. 

A final glimpse at Halfdome.
