There is a fascination with water.
We migrate toward water as soon as the weather starts to warm a little, camping next to a lake, river or a big body of water of some sort.
I remember one trip my husband and I made when our children were about 7 and under. It was a camp site friends had recommended. We pulled an RV to the spot and settled in and as soon as we got settled the kids started to ask where the water was. There was no water other than a public swimming pool. The kids had no idea what to do with themselves. I think they would have rathered been at home because we had dirt and trees at home. We hiked and rode bikes in the hot blazing sun and then returned home early, cutting our time short.
We all missed the water.
I think the fascination with water began with infancy. All of my children loved playing in their bathwater. The bathtub would be full of all sorts of floating toys until they outgrew them.
