I know this thread is kind of old but I only just found it. There is enough of us on this thread to have our own minature boxer bash in MA. And I have a few more boxer friends who I am sure would attend. So let me know if your still looking to get your boxers together. Although a Petco parking lot does not sound like the best place, lets find a park where we can let them run and play.
Next spring I have volunteered to organize a fund raising boxer bash for the Boxer Rescue group that I volunteer for
www.boxerbuddies.org
That should be a big one so I will be sure to let you know.
In the meantime lets get together some weekend before it gets too cold. I see we have people in the Boston area, Julie in Watertown me in Maynard which are all reasonably close, Shannonmac where is Fairheaven ?
