SITREP 1: Upon investigating the source of multiple sirens, I was informed by a LPSDeputy that a train derailment had jus occurred approx 300-400 yards away had caused a Sulphur Dioxide spill. He also informed me that we may have to evacuate. I put our chemical spill bugout plan into motion. In an hour and a half, my severely disabled daughter snd her equipment, bugout bags that weren't already in place, meds, money, weps, & clothing were loaded and we departed. I talked to the roadblock officers and ensured that my camper's storage garage was well clear of the "Hot Zone". We're currently checking into a handicapped & pet friendly hotel on the opposite side of town.
