TR Breakfast: 
Launch site will be Deer Trail. Breakfast will be at Denny's in Limon. 2455 6th St, Limon, CO 80828. The first launch will be at 8:00. Plan to be to be at breakfast about 6:45 and to leave after the first launch. Be prepared to track three exempt balloons. Note the assignments in the Tactical Calls area of this Web page. Each of you will have a primary assignment so you can focus on a single balloon. The roads may well be slick and muddy, so we will try to stay on paved roads. Wear good boots and bring plenty of bottled water. We will deploy from Limon southeast on US highway 287 and space ourselves accordingly. Be on the lookout for an appropriate student staging area near and short of the prediction. Stay in touch as Jim will update this page often. I am looking forward to this adventure and thank each and every one of you and your families for your participation. Note we will be using the PPFMA repeater for our repeater communications.
