Around here, I would say definitely. I graduated High School in 2005 with around 7 teams, now there are around 11 or 12, and there's now a large tournament that brings in around 20 teams. The rugby association around here has taken off, and there are more players per team getting involved. Honestly, though, the number of quality coaches hasn't grown with team number.
There have also been two college clubs started since I graduated, both created by guys I played with or against in high school.
