USA Masters Track & Field Rankings -- I'm ranked?!

Ladies,
OK - you find something new everytime that you Google yourself. Did you know that according to the website below, I am only 11 places below Olympians such as Nicole Teter, Jennifer Toomey, Shayne Culpepper?

No joke - check it out yourself. It's curious that there are no other Impalas mentioned (that I can tell.) Just my buddies Nicole, Jen and Shayne! (and they spelled Nicole's name wrong but got mine right!)

GO FIGURE! Maybe it will inspire some of you to run in a PA Track meet this spring so that you, too, can be cool enough to have your name on the list.
