"1. Has anyone found level ground without foliage to lay a strip?"
Yes Tinman86.
First, if you don't mind....a little advice. Always look at the readme file for any patch. It will only benefit you...
Now, to answer your question. From the Slovakia readme:
Emergency airbases without coded AI landing and spawn points: Drazkovce, Rohozna, Velka Luka.
Locations:
Drazkovce: J-11
Rohozna: P-8
Velka Luka: R-7
EDIT-I found several flat spots in just 5 minutes, so you should be able to also. They were on 'farmland', but large enough for a TEST Airstrip.
Did you try G-12? There is an island surrounded by a river that can hold a TEST Airstrip.
I'm sure you can find more spots if you really try...
