Ditto on coloring books, games, and craft projects. We also have a bug catching 'kit' that we bring along that includes a small wire cage, magnifying glass, tweezers, and a net.
We also always bring some kind of outdoor toys... a ball and mitt, bocce balls, and bubbles.
And since it seems to want to rain just about every trip we take... yes, I am one of those 'bad' moms that bring along the portable DVD player for bedtime. :eek:
Oh, the other thing we could not leave home without, is a sketch book and pencils. My DD loves to sit down and scketch the scenery when we're busy fishing. She can stay occupied for hours that way.
