Lao temples:
There's one by Windom, MN.
There's another in Farmington, MN.
There's also one in Forest Lake, MN.
And then there's that one in Monticello, MN.
Cambodian temple: I heard there's one just or in Bloomington, MN.
I ran into a Cambodian temple somewhere near Faribault, MN but it was closed when I happened to see it on the mountain.
Which Lao and Cambodian temple did you attended?
