Nope, I tried to get the captain to steer over to one end of the rainbow but it was on the east side of the reef and he didn't want to cross over it again. By the time we got to the dock, we couldn't get to the island side end of the rainbow because it had disappeared.
If we could have just made it to the end of the rainbow, you and I wouldn't be having the convo because I'd be living in SP instead of cyber-experiencing it here just to get my fix.
