DVD's really keep the kids ocupied while getting to the campsite.  You are right, once arrived TV is not needed.

I guess I don't understand why you would drive hours from home and go
through all the other efforts involved with 'camping' to sit out in the
nowhere and watch TV and movies.
Hell even if it was raining I'd rather go for a walk in it, or sit
under the
tent or awning and watch/listen to it; otherwise I'm out doing
something, or
sittin' on a log not doing anything, which is part of why I go.
After the first day's withdrawal the kids act like they've been freed
from
chains, with 'nothing to do' but run and play and explore- and bug the
neighbors, if there are any.
At night we watch the fire and actually ... talk to each other. We wait
for
the kids to fall asleep so we can, um (ahem) ... fresh air will do that
to
you. : )

I don't get it.

Cya,
Robert
