I'm spoiled here too. I usually get half a lane to myself but I come from a group swimming backgroud where we have up to 6 people in a lane. The people here are really nice too and I'm sure no one here would ever be that rude.
Congrats on your swim. It makes a huge difference to swim with faster folks. I just joined masters for that reason. I love the group, hate the 6 AM start time. But I am getting a good workout.
