I tried that IMC flying in uncontrolled airspace once, about 20 years ago. Good that I talked to ATC, good that I didn't know that I was not required to do that.
At one point the controller said: I suggest you turn to 180 degrees now!
I wondered about the wording and asked: What do you mean, you suggest?
She said: Well sir...I strongly suggest you turn, because there is opposing traffic!
If you guys are not required to talk to ATC, how do you get back out of the IMC conditions?
