The study of light nuclei at the drip lines offers a unique opportunity to test our ab-initio understanding of nuclear structure in the case of extreme proton to neutron ratios. With the advent of high-quality radioactive beams, these nuclei can now be accessed through transfer, charge exchange, or elastic scattering experiments in inverse kinematics. The very neutron-rich $^{9}$He nucleus has been a subject of active research over the past decade, and many peculiarities in its structure have been claimed. We have recently performed a measurement of proton elastic scattering from $^{8}$He to study the T=5/2 isobaric analog states of $^{9}$He at energies near the T=2 neutron decay threshold. The quality and intensity of the $^{8}$He beam at TRIUMF allowed for a high-resolution experiment with excellent statistical uncertainty, and the results of our study will be presented. At the other extreme, we have also recently performed a proton elastic scattering experiment on $^{9}$C at Texas A\&M University to directly probe the structure of the proton-unbound nucleus $^{10}$N. Preliminary results of this experiment will be discussed as well.
