Henry A Wallace - Vice President
Final resting place:
4909 University Ave
Des Moines, IA
Wallace was the 33rd Vice President of the United States, under President Franklin Roosevelt.
As you can see from the pictures, I visited him during the Winter, early in 2011. It's considerably easier to find during the Spring/Summer. Right inside the gates, there is an office. Go inside, and the friendly staff will be happy to give you a map which shows you exactly how to find his grave.
