teach your kids
One thing that really helped me increase my kids' enjoyment of disc golf was to teach them how to throw a roller... My 6,4, and 2 year olds can now play 9 holes with me (although they are typically distracted by the playground near hole #4 and let me finish in peace).
My 4 year old couldn't get the RHBH motion right, and more often than not the disc went backwards... her roller can go 50+ feet down the center every time.
My 6 year old could throw ~30 feet with difficulty, and her roller is getting out there 60~75 feet easily.
Give them some early success, and they will beg to play with you!
