Hi Nan,
We also have a men's group. We've found it was hard to get a group together every month but quarterly seems to work well. We've taken them on boat rides at the local park. They have wheel chair accessible boats. We've also taken them to local high school sports events to cheer on the students. We've had young men come in to talk to them about the differences between their times growing up and theres. We've also had men members of the staff attend meetings to interact with everyone. You could take them out to a big steak dinner. What about hosting a Super Bowl party? Hope it helps!
