Is there a masters group you can join?

I'm never very motivated to train for the swim (it's one of my goals for this year to do better). In fact I did a triathlon with a .75 mile swim last summer when I had only swum once since the summer before (unfortunately my swim time showed it too).

Some folks I know organized a weekly swim workout. Someone puts together a workout and a bunch of people show up and swim together. I find I'm much more able to motivate in the swim this way, than if I had to go to the pool and swim on my own (I much prefer outdoor exercise).

So if there's a masters group you could join, or a group of friends you could organize, that might be a way to motivate.
