I do not know any tujlub players in Texas. However, there is a small Hmong population in Dallas-Fort Worth and Houston. If you do find yourself meeting a Hmong in within that area, you should ask about tujlub. Every year, there is a Hmong New Year in Texas. Google search "Hmong New Year Texas" for further search. The only states I know where there are tujlub players in Minnesota, Wisconsin, Arkansas, Georgia, Florida, North Carolina, Colorado, California, and Rode Island.
Although you are not able to make it in GreenBay during the Memorial weekend in May, there is a tujlub tournament in Minnesota on July 4th Independence day weekend, and Labor Day weekend in Greenbay, WI. I will post up flyers when it gets close to the date of the tujlub tournament.
