update:

Unfortunately, this won't be happening this time, as I have a work comittment thats popped up right in the middle of the dates I posted.

As far as National Parks go, the information I was given when I rung was that they were still open, but pretty wet.

Hopefully I'll be able to find a time not too far away later this year, when everyone is free again.

Apologies to anyone who planned around this.
