Just to reiterate a couple of things:
1. There are two different divisions for this event. The Lambs is the beginner-friendly/Junior course and the Lions is the Pro/Championship level course. If you have never played the Lions, it is a challenge even for some very seasoned disc golfers with a couple of shots that will require throwing over or around water. If you are playing with a Junior 12 or under I would consider playing the Lambs Divison instead.
2. This is a Parent and Junior only event. No children over the age of 18 will be allowed to play with their parents.
Are we playing best shot? My son is 11 throws about 180-200 on average, should we change from lions to lambs?
No it will be alternate shot. I would consider switching.
