"Straw Filled Raised Bed....."

I bought 6 bales of straw this afternoon and filled the new raised bed.  I had a small space between the last 2 bales so filled it with some of last years straw mulch that had been removed from another raised bed to allow the soil to warm up more quickly.  I then covered the entire bed with more old mulch and began watering it in hopes of saturating the new bales prior to covering them with my growing medium, "Wholly Cow".  I won't be covering the straw until near the end of the month when the chances of frost might be over.
