Tom, if you hear anything in your garden near midnight please, please go back to sleep..... you do not want to have to testify in front of sane people that your iris garden was invaded by inebriated people with large gunny sacks wearing bandoliers, tutus, snake boots, hard hats, head lamps, brandishing, garden tools, bows and quivers, automatic weapons, wasp spray and silly string ..... led by a cat. ..... and I think someone said popcorn? (this to the Midnight Diggers, perhaps we should watch for traps? or having water hose turned on us. ok. bring ponchos or umbrellas.)
