Help boys become interest in swimming

I think one way to get more boys or teenage boys involved with swimming is by getting states to expect the sport of water polo. My state doesn't do it and a lot of other states don't do polo. But if more states adoptive the sport more young men would be involved with swimming at least in the high school level. Most guys at my high school in California during the 1970's played Water Polo in the summer and fall and swam in the spring. They were in better shape in swimming and could work more yardage than if they swam for only 3 months which is common for states without water polo. Water polo is so popular with teenagers in California that they introduce even girls teams in the 1990's. Most boys like a sport which is similar to hockey except that its in a pool instead of an ice rink. Also, US water polo would gain by having a bigger pool to draw from on their national team instead of 80 percent or more just coming from California.
