This seems to be a pretty boring day in history. Here's the most interesting tidbit I could find!
August 3, 1846 - An ominous sign of the troubles to come, the Donner party finds a note warning the emigrants that their expected route through the Wasatch mountains ahead is nearly impassable.
(Y'all know the Donner party? Right? The group of immigrants that got stuck in the mountains by snowfall and had to resort to cannibalism?)
