You haven’t lived yet . . .

If you have NOT been tubing in Lake Tahoe.  Add it to your To-Do list of 2011.  
If you don’t live near California any lake will do but the main ingredients still apply:

1.  tie multiple tubes behind a ski boat
2.  let the craziest boat driver take over
3.  more people the better, especially if they are new to the family, it’s a ritual in our family
4.  goggles optional but recommended if you have contacts
5.  life-jackets, ESSENTIAL
6.  hold on for dear life
