Dangling Modifier exceptions

Many spout off about proper grammar usage but are not qualified to make opinion.
I think I am right about dangling modifiers. I just thought of this experience that illustrates the observer position like a grassy knoll.

Sitting on the beach, I was cold. (correct)

Streaking across the beach, (it) was cold, (we) went real fast to see an ice ball.
Incorrect ((questionable): as to what was streaking, the ice ball or we)
Correction: Streaking across the beach, (we) went real fast to see the ice ball; it was cold.
(explanation: The streaking occured by "we" which is an act of swiftness and not nakedness.)

Streaking on the beach, (I) observed, nude women who were cold. (theoretical)
(the nude women did the streaking, but the observer position just observed streaking)
In the observer position, it becomes a commenting clause, and does not need to do the action but observes; the following clause makes it clear who/what did the streaking, whether streaking is of swiftness or nakedness.

The person who does the action must be in the slot after the comma and the participle clause. An "it" cannot streak unless it is an object like an iceball or an it.
