extension cords and rain

Most cords (outside type) are made to be connected with no problem, inside or out. Some folks make some simple covers that shed rain. I have on occasion just placed a small plastic bucket on top of the connection point. But, when laying on the grass, I always put a wooden block (since I always carry lots of lumber), under the connection point to get it off the ground. In the event of rain, rain water will drain around the plug (which is higher than the ground water potential), and also easier to spot if anyone is cutting through the campsite. It's simple to do, just put something under the spot where the 2 cords connect to raise the connection a little. Never had problem doing this, rain or dry. If I know heavy rain is expected (especially at home), I'll cover the connection with a Schwan's 1 gallon ice-cream tub bucket. They work great for all kinds of things like this and we have a lot of those buckets.
