Also, this is a good reminder that weird shit happens all the time and it's good to be prepared. If you're able, I highly recommend taking the free Neighborhood Emergency Response Team (NERT) training through the fire department the next time it's available. You get great training on how to respond to different emergencies. Once you've completed the entire course (which takes place over several weeks, with one class per week), you also get linked with the NERT group in the neighborhood you live in. There will be additional trainings that come up for both your smaller neighborhood group and all the NERTs citywide that you can join to keep your knowledge and skills fresh.
I just checked the website and there are spots open for training in January!
