Fish Daddy and I are headed for a looooong weekend in Portland next month, (19-22). Get to see the grandkids, 1 for the 1st time.
May have a little time to bum around. Any advice on places to visit? Koi shops

, gardens

, 'public' ponds

or any place else that might interest the mildly kichi

and maybe even the grandkids/kids/other grand parents *from over the pond*
(who we don't know).
Have heard about the Japanese Garden.
Thanx for the tips.
