NFHS Interference - Visual

[1231234]

I've been around Fed rules for many,many years.
Taught or helped teach the BB & SB rules for about 18 years.
Can't ever remember a rule such as the one stated here
RE: 3' to 6' etc.
I'd feel safe in saying it never existed. The only thing ever RE:Interference by "R" in a case like this is what Bretman brought up. I'm rather sure it never existed in any way in any ball let alone Fed BB or SB.
