I vote for April 27-28
reason; Easter is April 21, that means that Palm Sunday is the 14th. Since some of the clinic classes do not get off of the river until suppertime on Saturday, and most groups meet up early on Sunday, a lot of folks that would like to attend a church of their choice would not be able to attend.
( I usually boat with my wife’s blessings- if I miss too much church, I don’t have her blessings. Means no boating)
