So if I were to do a 5 Gal batch is it as simple as splitting the Recipe in half?

It is for the malt bill, but not for the hop additions. You would normally use brewing software to figure that out for you, unless you really enjoy complicated equations.

The real question is: where could anyone find Simcoe these days? Such a tease of a recipe! ;)

Morebeer! They did a great job rationing simcoe. I'm sipping on a brown ale dry hopped with 2 oz of the illustrious hop. Fantastically fresh.
