attending a team practice

[Andy]

I can't really see the rationale for attending a team practice. As others have said, scrimmages are one thing, but there are generally two or more teams there.

I was invited to speak at a HS summer camp/clinic once as an official. The AD/BB coach of one of the schools in a small Christian HS school league that I worked in ran a camp for kids in the league and asked if I wanted to speak for a few minutes and address rules questions.

It worked out well, I approached it from the point of "referees are human too, most of us played at some time and this is how we stay close to the game." I was really trying to recruit new officials from the kids after they got out of HS and college. I don't see where this was any problem or conflict of interest issue.
