[Rockhounds] Crater of Diamonds State Park

" Given how dry it is, I don’t expect they would have this problem"

Is it dry in Arkansas? Here in Florida it has been rainimg every day for
the last 10 days, and when we drove thru Texas into Arkansas three weeks
ago they were getting rain every day. Louisiana had floods.

I see it's forecast for dry this week but rainy the following week. Darned
hot tho.
