Grampa what do you and your friends at "SIMMPits Mind BBQ" do when you visit all those museums?
We donate our time and equipment to setting up WW2 two person fighter combat simulation stations with Aces High 3 running on both computers. We hang out on weekends to help kids like yourself and your father get setup and shoot at each other in simulated WW2 fighters.
In the end, this is a good idea but, the kind like those museums which will take donating equipment and your personal time to make it work on weekends. But, if you have yourselves prepped to help with sourcing inexpensive joysticks and computer help for the game. You may get a few interested and flying with us. You could even do a road show with an SUV, computers\equipment and lots of contact with museums to show up for weekend appearances. As an extra attraction, get each location to allow you an Internet connection to show interested guests the online game or, Messiah used to use his cell phone as his link to play the game from his computer.
