“2 words.....Water balloons.”
... Filled with Battery acid
Water balloons with water are enough the temps are gonna be in the upper teens - low twenties 8*)
No to the water balloons & no to the battery acid . USAF “Crash truck” with forward mounted “monitor” high pressure fire nozzles that can send hundreds of gallons of water a minute over 100yards. Roll one of those bad boys right up to the property line at the front gate & let it rip with a 10k gallon tank on board it will give the traitors,commies & assorted riff raff a rude surprise.
