I attended the annual Fall In 2010 miniature wargaming convention at the Lancaster Host on US30 in Lancester PA. I was only able to go for a brief time on Friday night because of work commitments, and not at all on Saturday as it conflicted with the Halloween weekend and previously scheduled events. It also conflicted with the annual MilitaryHistoryOnline.com Civil War muster at Gettysburg, which I also missed. Too many fun events on a weekend already chock full!
Jim Kopchak is an old friend of mine from the Cleveland area, where I spent 23 years before moving to York PA. Jim wrote a rules set entitled Civil War Commander, which has both regimental and brigade level options. His games are always fun and well attended.
