I'm definitely interested in Saturday morning group breakfast, and having that be our only community meal within our subgroup.
Friday night arrivals will vary drastically. Lunches are always best done independently since some people will go run trails during the day, Saturday night is the MRV huge group potluck and dutch oven competition, and Sunday morning is pack up and leave for most folks. I like the idea of hors d'oeuvres for the Friday night crowd, and we'll bring something simple if we make it up the mountain soon enough.
