re: What experiences from your past would you bring back for today's kids if you could?

Pretty much the "go outside and come back in when the street lights turn on".

We built tree houses.
We played pickup football/baseball/whiffleball/basketball.
3 houses had swimming pools in the s/d (water volleyball and water polo).
We played on dirtbikes and in creeks.
Every 4 years or so, we would have a street war (throwing tree fruits and nuts and taking prisoners).

The thing I feel our younger generation misses is moving out at 18 years old and "being poor". Figuring life out (maslow's heirarchy). How to be self sufficient. How to sacrifice today for a better tomorrow.
What purchases generate wealth and opportunity. What purchases generate debt and are burdens for growth.
