A loyal reader noticing the title of this post may be tempted to point out the hypocrisy of a free-market gent advocating such a position, but you'll notice that I am not advocating that the government pervert incentives by offering a subsidy to said businesses.
That having been said, I would highly recommend supporting some businesses that have been nurtured by the University of Maryland's Dingman Center For Entrepreneurship.
If you are looking for a board game, check out Wits and Wagers, distributed by NorthStar Games, available at Target.
The most successful Dingman company that I know of is Hook and Ladder Brewing, which in addition to making good beer, donates money from sales to good causes. I believe the bottling operation is quite new. So buy some beer.
