in our own separate ways. i planned on staying indoors the entire time. and then saturday at 12:00 came, and you see there's a live picture right now, the streets are clear. but saturday at 12:00, i ran out of food and alcohol. so i had to make a run for it several blocks in manhattan. >> you do look very sad there. >> but look at this. this was vista. this was down sixth avenue here, the shot that i took. >> doesn't look that bad, though. it looks slippery. >> it does. >> you can see the wall on the left side. i see, yeah. >> but the good thing. >> that's my little boy. there he is. >> with a perfect form. >> he waited patiently all weekend to be able to do this. we explained he couldn't do it saturday, but sunday it warmed up a little bit.
