Welcome Chef.

It sounds like you learned a lot thanks to that week. You now want to remember it for the future. What you do not want to do is become complacent, and next time look like those folks in hurricane country that, EVERY time a big storm is coming, have to fight for bottled water, batteries, etc.

The post about propane stoves is a good one. You can get a long hose to run from cylinder to stove at most RV supply stores, so that you can leave the cylinder outside and cook inside. There are also large propane heaters available for less than $100 that put out a lot of BTU's. They do take quite a bit of propane, so you will want a large tank, and a fairly easy refill...
