Abstract: We study the relation among the genus 0 Gromov-Witten theories of the threespaces $\mathcal{X}\leftarrow\mathcal{Z}\leftarrow Y$, where$\mathcal{X}=\c^2-\z 3$, $\mathcal{Z}$ is obtained by a weighted blowup atthe 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 CrepantResolution Conjecture of Bryan and Graber.b
