Dave - Sounds like you will have a bad week next week! Wishing you luck for surgery next week - hope you recover in time to join us.
Your question is very fair. What happened last year is that most people registered in June in the last 2-3 weeks. I sent out a reminder note yesterday to everyone in the range of NJMP. I expect there will be additional registrations as we get closer. That may not be ideal for you however, thats how it seems to work out. Not everyone can control the spouse, boss, kids, etc the same way you and I can!
Edited to add - I just checked my PM and I had 2 messages in there saying they want to come along and are sorting out the work committment situation.
