Alright, so my parents single-handedly got everything packed and ready to go at a moment's notice. After I checked on them twice (I think they were getting sick of my phone calls), I told them just to call me if they were forced to evacuate. That was quite a few hours ago and I haven't heard from them since then, so I'll take it as a good sign.
What's really cool is -- get this -- an Evacuation Plan ACTUALLY WORKS. Go home and make one for yourself right now. My mom was telling me how she just busted out the list we made 10 years ago, went down and checked off all the items, and bam, she was done. No stressing, no cursing, and no forgetting important things (unlike me flipping out over here in NorCal).
Being paranoid, I asked if all our neighbors had non-shingle roofs (our neighborhood had all shingle roofs before... total stupidity). Otherwise I was going to make my parents go over to their houses and water their roofs down for them.
So good news is I still have a house and my parents can still stay in it despite not being able to see anything outside. Air conditioners apparently filter interior air better than anyone would've hoped. Bad news is they're probably not out of the woods yet. Plus, my poor favorite Oak Tree out in the hills is probably not doing so well. But we'll see. Hope all is well with your families and homes.
