We started our fencing program at Modern Fencing Sports Club last year and absolutely love it. It is a lot of fun not just for our 6-year-old son, but for us, adults, as observers. A big saving that we didn't have to buy the fencing equipment, everything is provided by the club, and the classes last nearly 2 hours. Not much info on the website though, try this link
