Actually late April to late May are really prime times to go. The "rainy" season (which really means most of the time just higher humidity)is over. It is before school is out. That is what I would suggest really or the Sept October time frame as well. Prior to the "humid" season and after school is back in session. Seems like April to May may be the area to focus on for this group. Ken and I will be able to go then too.
