While the charm of the road north is real, the pot holes, mosquito filled puddles an impassable mud holes made it a nightmare sometimes. One of my favorite things to do in SP is to rent a cart and trek north on the "Rum Punch" tour. Coco Locos, the Palapa Bar, Lazy Croc BBQ, Rojo Lounge, Mata Chica, Portofino and sometimes if we feel adventurous, Belize Legacy (can't remember the new name)and Tranquility Bay.
If the road is nicer, more folks will trek north and those places will have more customers.
When the hand pull ferry went away, we missed its charm the first year, but the bridge has been so much nicer.
The old "Corona Freeway" project might become a reality.
Like Phil, I'm not quite sure how I feel about this, but like the idea that it will be easier to get to northern places we love.
