I have a buddy who raises homing pigeons with a 300 mile range. He uses them for weddings and racing, but it isn't like they have a union contract excluding messaging. The US military currently has no trained falconer program. I am unsubscribing and if you would like to continue this conversation I will locate another venue as I think this is against rules and I am always in trouble here.
Maybe one that is encrypted. Not unbreakable encryption, but sure takes up a lot of resources to break it.
