Creating a Rye Sourdough Starter in Colder Climates

This is not a question but an observation regarding the creation of sourdough starters in colder climates.

Colder climates create a real problem when it comes to building a sourdough starter.  Most homes in colder climates during the winter have inside temperatures running somewhere between 65 and 72 degrees.  In my particular case, my home never reaches a temperature above 72.  Because of these temperatures I find it very difficult to even activate a starter.  For those of us who are dealing with these temperatures I found a very easy solution.  I don't recall the actual website but I saw someone using an portable ice chest.  With that in mind I went to Target and bought a 52 quart ice chest for $19.00.  On the internet I found a Honeywell thermostate, in line, for $8.00.  I also went to home Depot and bought me a 15 foot, cheap, extension cord, a 25 watt under the cabinet light buld and a light holder.  All of this I installed in the ice chest and added a cheap stove thermometer.  This I used becasue most in-line thermostats are not accurate.  After playing with the thermostate for a few days I was able to achieve a constant 79-80 temperature.  Now I can make sourdough starter easily. No more problems with home temperatures.
