I live in Tuolumne County and have spent a tremendous amount of time looking over the deer there...even hunted that exact hunt the first year it was offered as a choice (pre-preference points). You NEED weather to get the migratory deer out of Yosemite National Park and into the hunt area. There are some "local" deer in the western portion of the zone....but unless you are really familiar with the country I wouldnt count on that. Last year 2 friends had the G-37 tag (Anderson Flat Late Rifle)...it was terrible. No real migration....most deer stayed in the park until the snow storms finally hit after the season closed. Tag soup for both of them.
As far as the terrain, there is some country that is glassable over on the south side (Mott Canyon and the Merced River Canyon) but most everywhere else is pretty brushed up other than a few scattered pockets. Most hunters I've observed just road hunt until they spot something...then they try to put a sneak on it.
If you draw the tag, and you get the weather needed, I would suggest hunting out of a tree stand along the migratory cooridors along the park boundary. (I can help you privately with some info on where to locate these well traveled paths). The individuals I know that have been successful on this hunt all took their bucks out of tree stands during big storms.
