Bread-Bakers v101.n050.3

Hi!
  I have been out of the bread baking hobby for about 6 years and now that the
crispy cool weather is starting and my little boy isn't so little anymore,
I'm ready to get baking again!  I'd like to start by making my own sour dough
starter (or purchasing some if I have to) and making some good loaves of
crunchy sour dough bread.  Any suggestions on how to make my own starter and
care for it properly?  Thanks so much!
