TR Breakfast: 
Hello Trackers, Looks like a possible icy adventure Saturday morning. Sure am glad Mark is driving:>) Here are some fine words from our flight coordinator, Tom. Launch site confirmed as Windsor, with launch at 7:21 AM mountain time. The latest predictions have us going east with landing somewhere near Fort Morgan. For those attending the launch, please be aware that conditions will be icy, and there may be holes or ditches concealed by snow. So step carefully and dress warmly. Likewise on the way to landing site, the recent freeze-thaw cycles may leave icy patches or mud on the back roads. Drive with caution. It WILL be slick at 5:30 am! Additionally let's be assured we will not head into the recovery site until we have clearance from the landowner or if Alpha requires us to secure the parachute. Stay safe and warm! Breakfast will be at McDonald's in Ft, Morgan at 6:45, with trackers leaving the area about 7:15 am.
