There used to be a 1003 T-bolt about 100 feet from my grandparents' house in Nebraska. They used to do a noon blast every Saturday and a 3 minute test every second Tuesday of the month. Later, they changed it to a 3 minute alert and a 3 minute attack every first Monday of the month. I was usually expecting it, but a few times I got caught playing right by it when it went off. It used to startle me so bad it felt like the ground was giving way beneath me
