Your post was so funny! I think I love your DS.
I just wanted to comment on track and field... it's great for taking anyone of any ability at a starting point and everyone can have measureable improvement. If he cares at all about stats, he could track his progress in terms of effort + time.
It can also be a social sport with a real mix of different personalities.
Good luck to him - hope he likes it.
Thanks Seablue! I think he'll like it. Our club will let him do mini-javelin, which is the main reason he's excited. A love of Greek mythology combined with an interest in physics... the geekiest javelin thrower out there! He will love the stats part too and is even looking forward to picking up a running event as well.
