If you're driving to NB, here are a few things you may want to see along the way

NB Botanical Gardens - St. Jacques, NB (exit 8)

Noah's Ark? - Florenceville, NB
A note about the ark: This is NOT a tourist attraction, but it is pretty cool.
A friend of ours used to live close to the ark which is how we know about it.
I believe the ark is used as a school. I don't think it would actually float.
To get to the ark, Exit Burnham Rd (left - up the hill) off the Trans Canada
(Route 2) and follow the road for a short distance. Ark is on the right.

Longest Covered Bridge in the World - Hartland, NB (exit 170)
