I played the game for a few minutes this morning. I went and sold my fish from yesterday, then I walked over by the waterfall. And there it was…a rainbow! It’s the first time I’ve ever seen the rainbow. Apparently they show up in the morning on clear days when it rained the day before. I rarely play in the morning, so that’s why I never saw it before.
Update: Here is a video of the rainbow:
Replaying for GC and saw one for the first time today myself! It’s a great site!
