I helped out as a volunteer at the Seattle Classic tennis tournament today.
The tournament is sanctioned by the Gay & Lesbian Tennis Alliance (GLTA). The GLTA is an international body that oversees an impressive worldwide circuit of tennis tournaments (check out the table below).
The tournaments do not have prize money to speak of, but it is a great way of encouraging the LGBT community to participate in the wonderful sport of tennis (of which I am a lifelong fan).
