Counting only money I spent, and not counting any help early on from my parents or money from those I traveled with, I estimate I spent:

Travel costs:

- approx. $2000 USD for each of Worlds 2007, 2009, 2011 including all traveling costs.

- approx $450 USD for each of US Nats '04, '06, '08, '10 and Worlds 2005 and 2013

- Approx $350 USD each for 3 competitions

- Approx $250 USD each for 11 competitions

- Approx $100 USD for 2 competitions including Worlds 2003 (my parents paid most of this one)
