If you like the outdoors, check out University of Colorado Boulder. Has Aero and punches way above its weight in math and physics. My niece sounds similar to you and turned down higher (generally) ranked schools. Started off majoring in aero and math and eventually moved to math and physics. She liked the math department so much, that despite other opportunities, she stayed for her doctorate.
It’d be a likely for you and you can expect merit, plus, lots of support and TA opportunities if you end up in the math department which is an easy minor with aero or transfer from aero.
