A Frozen Garden?

My poor little fledgling garden, not even a week old and the forecast a few days ago was calling for super cold rain and snow possibly down at 1500/1000 ft.. What???  The forecast has since been revised, higher snow levels, but still probably cold enough to do a bit of damage to my little seedlings.  My Dad had suggested  building a portable greenhouse to keep it from freezing, so I went to Lowes and bought some supplies (which the husband told me later we had most of the items already, oops - communication has never been our strong suit...).  I must say I felt rather industrious picking out pvc pipe and connectors and even a pvc pipe cutter (to my male readers, please stop rolling your eyes at me).  After lunch Noah and I rolled out some burlap and wrapped my new baby citrus trees and then I attempted to use the pipe cutter...after several minutes my prior feeling of industriousness was gone and in a moment of frustration I asked my almost 5 year old if I was not talented enough to figure out how to open the the pipe cutter if that meant that I should not be using the pipe cutter...he said, "Yeah Mom, I think it does..." and he kind of chuckled as he said it.   Honest kid...love it.  I did finally figure out how to get it to work  (have all my fingers left too!).  Shay came home in the middle of my "building" (thankfully) and took my maybe-ok-and-probably-more-complicated-than-necessary idea and modified it into a simple, but very viable solution - it's like he's has experience in building things or something?!?  So,we'll see how my "winterizing" techniques stand up to the great Southern California blizzard of 2011, HA.
