After playing one on one basketball with the neighbors wife.
I drink beer everyday (4/5 when I get home from work, a FEW more on weekends) so anytime is good. But if I had to single one out it would be after mowing the yard. There is just something about standing in the heat of summer and looking at the beautiful accomplishment after you mow.
While fishing is also another great one. Bait the hook, toss out the line, put the rod in the holder, get a cold beer out of the cooler and sit in my chair feet propped up on the cooler watching and waiting for a catfish to take the bait. It is just so relaxing, I really do not care if I get a bite.
Golf course and relaxing on the beach are also good choices.
