comment How to show a graph is not Hamiltonian?
Oops, upon reading my post again I realize I forgot to add the property that $G$ was 3-regular. My bad! But nice counterexample for the original post.

comment Proofs involving subtrees of a tree
Sorry, I didn't notice the typo. Indeed it was a nonempty intersection, and I've corrected the post.

comment Constructing a 3-regular graph with no 3-cycles
No, there cannot, but I'm having trouble writing this "formally". Do I simply write that this is because $k+1$, say, would only have edges between $k$, $k+2$, and $k+(n+1)$, and so $k+n$ is not included?
