I was trying to hurry and finish a round at Pier Park in Portland to beat a rain storm. Pulled my drive on 16 into the thicket on the right. I searched it and a possible rollaway down a hill further from the basket (toward 17) and then it downpoured as I continued my search. After getting drenched for about 30 minutes it let up and a group who had taken cover during the rain played through and the first guy to approach the basket says, "Hey, you're not looking for this disc by the basket are you?"
Now, I immediately put my bag where I think the disc is or where I lost sight of it as a way of orienting myself as I search. (This backfired once when I actually set my bag on a disc buried in the leaves which of course I uncovered by giving up my search and yanking my bag off the ground in frustration.)
Then, I check the easiest places for it to be at before diving into the worst-case scenario places and also do a walk backwards from the basket toward where I think it is. I've had several occasions where a disc is hidden by a log or tree or something looking at the angle facing the basket but completely visible at the angle facing the teepad which sounds obvious but is actually counter-intuitive as you tend to assume the disc will hit something and stop behind it and not somehow maneuver itself in front of it.
I play alone a lot, and notice a tendency when playing through a group to rush to where I threw without pausing to make a mental note of where it landed first, which is my normal routine. Taking 5 seconds to make a mental picture of what it landed near often saves 3 minutes of wandering back and forth.
