For what I thought was the second day in a row, NOBODY interesting was visiting the town. So after I did the fossil digging, weed pulling, and selling off what I caught last night, I decided to head to the island.
There I found that the wetsuit was FINALLY being sold, so I scrounged up 40 medals, and bought one.
When I got back to town, I used the wetsuit to swim over to the part of the beach normally blocked off by my town's waterfall . . . and saw a shadow around the corner, on the sand.
For all I know he might have been there yesterday too, and I just could not see/get-to-him then.
His questions involved where geoglyphs and alpacas were found (Since my town did not have geoglyphs, that ruled out here ;p ). Of the four answers he gave me, two were actually both likely; Chilie and Peru, since they both have alpacas & geoglyphs. I chose Peru, and he said it was the correct choice, so now I just need to wait for the letter delivery.
Just thought I would share this story with everyone else: If nobody interesting has shown up in your town, try checking the beach! You never know who you may find.
