Some non-spoilery 20/20 hindsight logistics advice for ETPH#3:

• Given a nudge that there's a choice of driving or walking between locations, driving is awesome. Walking is scenic… but you can take that scenery in during the drive.
• If you're bringing golf clubs for other folks to use, (1) you are a sweetiepie and (2) maybe tie some notably-colored yarn or something to the handle. You don't want other folks to mistakenly retrieve your club instead of their club.
• If, close to the end of the hunt, you're faced with a choice: wait to sit in this area if you want to order food, sit in this area if you want to sit and solve with no food—don't assume that the wait-for-food is finite. Maybe it's eternal. Look around: do things seem crowded? If you're hungry, maybe you should go sit in that other area and haul out your snacks. (You did bring snacks, right?)
