TR Breakfast: 
We have an impressive set of trackers for this adventure. All trackers will head for the recovery of EOSS #213. At some point, we will split off several teams to pursue EOSS #214. Standard drill. Breakfast is at the Limon McDonalds at 6:30. The EOSS #213 payload should be overhead of McDonald's after 7:30 a.m. Grid References have been posted as well as the test. We will use the PPFMA Pikes Peak repeater on 448.450 for the bulk of this mission. Please check your radio configurations as it has been a while since we used that machine. There is room for a tracker to ride along on a couple of these teams. If you are interested, let Marty know and he will make arrangements. Excellent chance to ride with Tom, KE7KCK. If the flight goes to November 1, you will need to adjust your clocks back one hour for daylight savings. Looks good for October 31 however. There are several new student groups for these flights. University, High School and Middle School. See Tom's list above. Watch for parent vehicles in the caravan. Please greet the students and learn about their experiments. Thank you all for your participation this weekend. - Marty
