Do you mean most enjoyable CD activity or overall?
For CDing, that is really hard. I suppose if I had to pick one, it is makeup and makeovers (or just visiting makeup stores). I just love talking makeup with the artists, getting tips, and trying out the latest trends trying for a feminine facial presentation. Fun to experiment and practice at home too. Close second is getting dressed up and getting out to the mall for a day and interacting with people.
Beyond CDing, there are many things. Cars, sports car racing , autocrossing, photography (got a Canon 80D this summer), fishing, skiing, hiking, golf. So many activities, so little time, sigh.
