Quoted from Mr68:
Not a service but I've always thought a pinball housing community would be cool. Kind of like a golf course community but with just the club house that each neighbor would set up and maintain a few machines that everyone could enjoy. Also a series of sidewalks connecting the homes where people could move their machines for sale, trade or temporary loans to each home collection.
Not likely to happen but fun to consider.
A walk-in basement in every home!
