I may be repeating, but here is some of the stuff I would consider.... If there is any dirt/sand around you may want to have a pail & shovel or some construction trucks. Various outside games and activities, balls, cornhole (bean bag toss), kids horseshoes, bubbles, water toys (water gun or those balls that soak up water) etc. A bike of some kind is always good. Also, don't forget to bring his favorite toy from home!!!
