The "joke", as you so crassly put it, was the sincere advice of legendary naturalist/ranger Carl Sharsmith, with whom I studied for a couple of weeks one summer in Tuolumne in the 70's. The story goes something like this:

But the advice is valid. If you are seeing something for the first time, why place a camera between yourself and the experience. I wandered around the Sierra for many, many years before including a camera in my kit and committing experience to film.
March is not a conventionally scenic time in Yosemite, particularly this year, with so little snow. The high country roads are closed, save Glacier Point Road as far as Badger Pass. The Valley is brown and will not see new season growth or leaving trees for another few weeks. The waterfalls are barely running and the streams are low. Still a day in Yosemite is still worthwhile at any time, and I would suggest walking some of the circumnavigating Valley trail sections (23 miles) or partial ascents up the 4 Mile Trail, Yosemite Falls Trail, or Old Inspiration Point for lesser known vantage. If you're lucky, it may even snow by the 22nd. If still available, sign up for inspirational "print viewing" at the AA Gallery. That's something unique to the Valley.
