Theodore Roosevelt was part of the Rough Riders, the first volunteer cavalry division in the United States. He led the charge up San Juan Hill. On that day, the cavalry division was without their horses. He led the charge anyway.
If you really want to read about manly presidents, this is the article to do it. Though honestly, they don't do George Washington proper justice in just how awesome he was.
Theodore, on the other hand...well, this is what they have to say about him:
"Roosevelt received letters from army cavalrymen complaining about having to ride 25 miles a day for training and, in response, Teddy rode horseback for 100 miles, from sunrise to sunset, at 51 years old, effectively rescinding anyone's right to complain about anything, ever again. "
Also, is that Booster Gold, HotandCold? Because that's a really awesome Booster Gold.
