The summer before his freshman year was the LAST time our son lived at home. He played on two local teams made up of good high school and junior college players.
Once he left for college in the fall he never came home except to visit.
The three summers during his college career he played in the Great Lakes, Atlantic and New England collegiate leagues. In each case he would have about a week once the season was over to come back to California for a visit.
Once your son knows where he will be going to college, the only thing to be accomplished is for him to be in shape and prepared for the rigors of collegiate life. My son got all the baseball that he needed while having one last summer with the family.
To this day, my wife complains that my son gave up friendships and family time to pursue his baseball dream. With that said, ask yourself "what needs to be accomplished?"
