I'd like to thank Bob Rocca, who made it possible for me
to get to know a lot
of Pros locations during two location tours :)
Kudos for his hard work; to visit locations is one thing, but search and
find them another.
Mixed locations, not only Pros
And here's a link for the ultimate book about 'The Professionals' by Bob Rocca, which is definitely
a must for every Pros Fan.
It can be ordered here
Go and have a look, I know you want to!
