Good question. Howard N mentioned in this profile that he belonged to several camera clubs, so I Googled my town and found one that meets nearby. I'm going to the next meeting. When I had a high school athlete, I met a couple of professional photographers while shooting football games, and I learned a lot just by watching them.

Change the city to where you live and topic to photograyphy. Look for a photography group and join. More importantly become an active participant.
