It seemed a little rude to walk in about the time they were wrapping up and presumably join in on food, so we decided to leave. We had a nice second breakfast with hot chocolate at a McDonald's before coming home, and laughed about it pretty hard.
I hold no illusions that a 1-hour drive every week will be a workable solution. But finding a decent gathering that could be a once-a-month thing would be great. More importantly, it's possible someone there would know somebody closer to us, perhaps meeting in a home or something. That would be great.
