One thing I forgot.  My wife "made" me do this for my first solo.  If you are going out solo get a set of dog tags made up.  Name, phone number, blood type, any allergies or other issues on them.  My first set was the ones from the machine in PetsMart because it was very last minute (remember the wife thing).  ;D  Then I got a "real" set later that I use a lot now.  Just a thought...
