Big brothers big sisters and other larger non profits is a harder nut to crack as mentioned, lots of legal BS. Find smaller groups in your area that can point ya in right direction. I’m a fan of showing up in offices, introduce yourself, have a short conversation and ball is rolling. Emails are so impersonal when it comes to this stuff.
If you need help with some kids on the Eastside I can forward off your info. Shoot me a PM.
That bass tourney on Big Marine (2-3yrs ago?)was the last time I heard of that big brother/sister event happening Dutch. Forget the fellow who put it together but remember him saying it was just getting harder and harder to organize every year.
