TR Breakfast: 
Thanks to all the trackers who have responded. Breakfast will be at Rookies in Strasburg, 1323 Monroe Street, 80139, 303-622-9750. They are full service and open at 6:00. There will be very few repeaters, if any, in the recovery area. Let's adhere to the simplex frequencies for each balloon. EOSS 232: 446.100 MHz, EOSS 233: 446.150 MHz Bring plenty of water and some food in case this goes long. Mike and Chris will come up from the south and eat at Denny's in Limon. We are going to revisit the recovery area of EOSS 224.
