One if by Land, Two if by Sea, Three if Deductible: Paul Revere submitted an 
expense account signed by John Hancock for travel expenses and horse rental 
for the first of his famous rides. He billed the Committee of Correspondence fourteen pounds, two shillings for expenses on his Boston-New York trip to deliver the Committee's account of the Boston Tea Party to the Sons of Liberty.

Although Paul Revere was reimbursed for that trip, he often rode as a volunteer,
paying his own expenses. In that spirit, many Americans work as volunteers for 
charitable organizations and receive neither compensation nor reimbursement of expenses.
