[what's up]

I'd like to know how many Senators are buried at Arlington.

And how many Presidents?

Just found my own answer on Presidents.

Only Kennedy and Taft are buried at Arlington.

The only other President to be buried outside of his native state is Woodrow Wilson who is buried at the National Cathedral.
