Well I just reserved my hotel suite for my son and I to attend Historicon 2009 in York, PA this July...I am beyond excited about it. If you've never heard of Historicon it is pretty much the largest yearly wargame convention in the country.
I plan to not only partake in a few games there but to bring back great ideas for the club. They also have an entire hall of wargaming merchandise which I will certainly take advantage of. Click the links below for more information.

In addition, my son and I will make a side trip the U.S. Army Ordinance Museum in Kentucky which features loads of WWII tanks from all nations!(I've always wanted to see a Panther tank up close and personal!)
