Hi There, I think you're heart is definitely in the right place but, you have to consider the overall experience. True, scouting has a great deal to do with the outdoors but it also builds friendships that last a life time and are well worth the time spent now. I was in a cub pack and a troop as a boy and then i lost interest.When my son joined I got involved again and found 2 very old friends were still involved with their sons.
We've spent afternoons talking about old times and boys in our old troop and those are some of the best memories this middle aged scout has. So why not give it a try and then let your son decide, afterall scouting is suppose to be boy run! And from the sound of your letter he'll do the right thing just like you taught him too!
