Thanks, DD.  I kind of expected that was going to be the recommendation, but I wanted someone with more knowledge than I have to confirm it. 
   My mom and dad raised me to be generous with others and reluctant to spend on myself.  This is a wonderful opportunity to throw off the shackles and splurge.  Besides, if I invest a little in this trip, it increases the odds that I will be back frequently.  But, frankly, it feels weird.  Only a relatively few short years ago, I would have used the map one of the outfitters sent m way back when, and I would have had a very enjoyable trip with a $5.00 compass.  Feels like overkill.
