I like to call him "The Conservation Crusader". John Muir is one of my heroes. He spent his life working to increase appreciation in others. He did a wonderful job, especially when he convinced Theodore Roosevelt that Yosemite should be preserved for eternity. He is responsible for our National Parks. This is the perfect item for any nature lover. Whether you're drinking your morning coffee, evening tea, or something in between – this mug's for you! It's sturdy and glossy with a vivid print that'll withstand the microwave and dishwasher.
