The
Planning Calendar is my go-to source for, well,
planning.
The AP calendar has too many events to sift through, and the OUSA calendar only includes events after they are sanctioned.
BTW, for the West Point A-event, that
first OUSA page only has links to online registration (in that annoying i-frame -- unlike the link from
here), plus the registration list.
*Edit 4/09/12: Thank you Janet for adding the
W Pt event link to that page!
