This is a little off-topic, but barely.
While Floss and I were volunteers with the Red Cross in Sept, we got deployed to help administer a shelter for last-minute evacuees (many of whom were special-needs people) from Lake Charles who were leaving on buses on Friday, Sept 23, too late to really get out of Rita's way. Some were already evacuees from NOLA. We all went to DeRidder LA and rode out Rita in the high school gymnasium with no power and no communications....for three days. There were about 20 of us vol's and about 400 evacuees.
By Monday, someone showed up with a Globalstar satphone. I have used one since 2001, so I helped the other volunteers use it to let family know we were all safe. It's not that complicated, but there's a few tricks that are helpful to know with those things.
You can also do data transfers, but that's slow and expensive and you need to use a car kit and....... better left for a previous thread, LOL.
The evacuees finally got picked up a little after midnight Monday night and were taken up to AR. We then drove back to Baton Rouge, arriving near dawn. We got Tuesday off, LOL.
