Bears holiday 1968

This is a book I had as a small kid, published in 1968, and its probably the first book I had that had surfing in. Having said that its not exactly surfing, its just stacking it into a big clump of rocks ; enough to put a small grom off for life. Papa bear was a bit of a know it all - you can tell by his bathing suit - and he spends the holiday trying to teach his son about beach safety, with predictably disasterous results.
