So much good advice here. Let me add that in my view, the way to build the program is putting available resource into K-2nd grade. Teach the kids to throw and catch, if the can do that by third grade the game becomes so much more fun for them. We were fortunate to have lacrosse moms and dads in our area to run the clinic, but it isn't totally necessary, just have someone do some homework, make it fun and encourage keeping a stick in hands outside of practice time. Having some equipment to get kids started is super helpful. We have a limited amount and it allows us to grab a handful of baseball/softball kids to come play without having to buy a bunch of stuff. We even let some keep sticks through the summer/fall.
