We all have an area we have procrastinated on or not had the funds for. What's one major thing you have yet to implement in your overall survival plan (OSP). Minuteman's post on preview of a SHTF got me thinking about last minute preps. I am sorely lacking in a convenient back-up heat source. I have a fireplace with 2 whole house blowers built into the stone. I can keep my house at around 68 when it's 20 outside with this fireplace. But it is grossly inefficent. I have kero heaters that I run with diesel. Work well but are smoky, stinky, messy, loud, and need a supply of D. Could be hazardous during a panic. Currently, (Last 5 years) have planned for a woodstove and an Outdoor Furnace like http://www.freeheatmachine.com/index.html What do you still need to do before things get rough?
