When Kruesi finished making the phonograph Edison put on the tin foil and then recorded the nursery rhyme Mary Had a Little Lamb; Edison's daughter Marion was at the time nearly five years old and his eldest son was almost two. Edison then adjusted the reproducer and the machine reproduced it perfectly.
Spring in Yosemite National Park. Spring is by far the best time to visit Yosemite Valley. In May the waterfalls are at their peak, the wildflowers are blooming, and the summer crowds have not yet arrived. Daytime temperatures are often divine, but be prepared for chilly temperatures at night.
First the good... We stayed at Wawona the end of August (our very first time in Yosemite, and first time in years since me or my boyfriend have camped in tents). The park rangers were super friendly and informative as we checked in. Wawona campground is lovely, but it's also very dry and dusty due to the drought.
