Have you considered starting a private for-profit club? There would be no need to rely on the government and the club could offer members benefits for joining and paying an annual fee. The club could then use money to lobby members of the legislature to support gas engines. Many Texans would probably be more interested in a private club. Just an idea.
A cool thing to consider would be a club hosted state bike-a-thon. A week long bike ride all around Texas would be sweet and bikers could ride in a loop through several of the major cities.
The most important thing however is to get more people in Texas to be interested in motorbikes of all kinds so that there will be more support for motorized bicyclists.
