That was definately an interesting sight - we always see the trails from airplanes, but this was clearly "rocket" powered. From where we were it looked like it was coming towards us "OH NO!!", but then it disapeared.

Shells are plastic decoys that usually have removable heads and can stack within each other for transport and storage. Full body decoys are the whole bird with feet. Silo's are the outline of geese - usually feeding and sentry's, cut out of thin wood with a metal stake to stick in the ground. Full bodys are usually the most expensive - then shells - silo can be made very cheaply.
