Having progressed a number of days beyond the Vernal Equinox, I have noted that at 7:00 a.m. MST, the sun is breaking the eastern horizon here in Castle Rock, Colorado, and illuminating the field at Douglas County High School, a favorite launch location.
This is the time of morning at which I am finished with my daily workout ritual at the local rec center.
This means that it's time to start thinking about resuming my early morning 'shoe box' rocket launches which I began conducting last summer.
I have only to wait until the morning air temperatures start reaching into the mid-50s.
Better start getting some birds prepped....
