  We study the relation among the genus 0 Gromov-Witten theories of the three
spaces $\mathcal{X}\leftarrow\mathcal{Z}\leftarrow Y$, where
$\mathcal{X}=[\c^2/\z_3]$, $\mathcal{Z}$ is obtained by a weighted blowup at
the stacky point of $\mathcal{X}$, and $Y$ is the crepant resolution of the
$A_2$ singularity. We formulate and verify a statement similar to the Crepant
Resolution Conjecture of Bryan and Graber.b
