Can you take a bad photo at Yosemite?

Well my trip to Yosemite National Park is coming up Wednesday and I'm just noticing that today's weather forcast shows a 40% chance of snow Friday and Saturday, and the park service says that the recent warm weather has caused a lot of snow to melt and make nice waterfalls earlier this year, so I'm looking forward to my first trip there. I'll be taking all my camera equipment, so with any luck my photo page will be bursting with new images of everything I see. I plan to take 2.5GB of compact flash with me.
