I do enjoy walking, but I can only get comfortably around the flat courses or courses with minimal elevation changes when I'm using a push cart. I walked a hilly course (Poppy Hills for those of you who know it) the other week and started to lose my legs around hole 13. This caused me to start spraying my shots and I double bogeyed my way in to the clubhouse... I'm going to make an effort to get out and walk more courses this year, and maybe, after some "training", I'll give the legs another shot at Poppy Hills later in the year.
