I recently read this collection of stories while on a nice tropical vacation where I did a couple of dives - so was in the mood. Below, I have broken down some of the positives and negatives that I took away from this collection:
The positives: This is without a doubt a comprehensive collection of writings - in terms of the time period covered and styles of writing (humor, poetry, etc). I thought that some of the stories were really great - couldn't help but laugh at Dave Barry's description of diving. I found a few of the older pieces very interesting due to the historic perspective / context.
The negatives: Any time you take on a project to complile a collection this large across different writing styles, it should be a given that all pieces are not going to appeal to all readers. About 25% of the stories simply did not appeal to me.
Secondly, there also seemed to be a recurring "What my first dive was like" or "What it feels like when you are down there" theme. I also found this a bit tiresome after awhile. As a diver, unending explanations of how clear and blue water is, the sense of weightlessness, etc got to be a bit much. Almost drove me to the best example I could think of - a bottle of Bombay Gin.
Closing: A large enough body of work that I think that every reader will find some of the stories very worthy reading. Light enough for a good vacation or bedtime read. Worthy enough purchase - I think a good gift type of purchase for that diver's christmas fin.
