swimdad99 mentioned the NCSA cuts, coaches from both Dartmouth and UPenn were in attendance at this meet last year (NCSA Junior Nationals in Indiana) and may or not be at the meet this year, Brown and Yale coaches were there as well. The coaches can observe you during the meet and are not allowed to talk to you until after the finals session of the last day. I do not know if your club team is attending this meet but if so, it would be a good idea to attend if you can. You mentioned earlier that you expect to have a strong long course season and this would be an excellent opportunity to showcase your talent.
