How Fast Are You?

While swimming in our hotel pool, I noted that they had three swim lanes; fast, medium and slow.  While I can understand the concept, I am just not sure how to classify myself.  Do I start out in the slow lane and move up if I start running into other swimmers?  Or do I start out in the fast lane and move into the slower lanes if other swimmers start to run into me?

Salt Water?

While swimming in the pool at our hotel, I noted that it was salt water.  This really surprised me so I asked the attendant.  She said that salt water pools were becoming very popular.

I guess is it like swimming in the ocean only it is inside.  Since it is salt water, jellyfish and sharks could survive in it.
