"My older sister went to BLAIR High School"

[twana]

Would that girl be referring to
Montgomery Blair High School
of Silver Spring, Maryland?

It's not too far East of Germantown really..
you know, where Heather, Mike, & Josh 
attended Montgomery College ..

.. and Ed & Dan actually did.

Black Hills Park is just West of Germantown.
and just North of Black Rock Road.
I guess this is where Ed got the idea for the name
Black Hills Forest.

Well, I wonder why they didn't film in Gathland Park
just West of Burkittsville. That location would have
served the mythology perfectly for the location 
of the house of the old hermit named .. Rustin Parr.

That's Ed's sister, by the way.

I figured there was no Blair High School and that it was just something she was told to say for the movie.  The film crew planted people around town for the actors to get information from.  The man in front of the store, the two fishermen.  Mary Brown.

I've heard Ed say that his sister went to a Blair High School,
and that's where he got the idea for the name "Blair Wtch".

So .. Ed's sister instead says that it was her older sister, not herself,
that went to a Blair High School.
Interesting behind th scenes stuff..
