Are you doing the Lake George OWS? I just signed up for the 2.5K, which will be my first non-triathlon swim event (well, since high school 20+ years ago!)
I am excited that you are doing it! I have been having the worst time convincing my tri club friends to try an OWS race. The 2.5k is only a little more than the swim in a HIM. I don't know if the swim starts from the same place as the swim for the HITS North Country HIM in June, but the bay area where the swim is, was really nice last year. Clear, calm, no weeds or mud. Very friendly swim venue.
ETA: I was between the 5k and the 10k, and, confession: the start times made the decision for me. I live almost 2 hrs away, and the 10k and 2.5k start really pretty early! The 5k is a little later
It seems like the race is in the same place - at the Hague Town Beach. It was a great swim (with a crappy bike and hilly run). I'm excited about seeing what I can do with just a swim. I'm not really sure how to push it because I'm so used to keeping it calm for the rest of a tri. Hmmm... It's probably not going to be great (especially since we'll be out of town that week for a Jimmy Buffett concert!), but I'm looking forward to it!
