Between Crystal River and Hernando, Florida, 6 miles west of the Withlacoochee Trail
I've had several since 1999 but have settled on my beloved 2001 Litespeed Tuscany and my latest, a 2015 Cannondale Supersix EVO carbon
It depends on how big the hills are and what kind of shape you are in. If you are new to cycling you may want the triple. You can always swap components later or get another bike.
We have hills and I ride a double without many problems.

If you have been riding these hills on a mountain bike or hybrid, you will have some idea of how low a gear you will need to get up. The easiest way to get a lower bottom gear is to get a rear cogset with a wider range, but you dont get as slick shifting. If you get a triple you can have a close ratio cogset at the back and still have a real low bottom gear. However a lot of road bike riders sneer at triple users.
