Today I rode on "real" hills in southern Indiana - I was in the granny gear more than the entire time that I've been riding! Ok, so that has only been 7 months but work with me here

I only had to walk one of the hills - it was on a detour I wound up making... I could have ridden the remaining couple of hundred feet but I was going 2.9 mph and could no longer hold anything remotely resembling a line. It was a narrow twisty road and I was having to weave back and forth in the lane to keep going. I pictured a pickup truck barreling up the hill...and walked it to the top

My "detour" kept me from climbing the 1.5 mile hill that I was told about, but there certainly were some pretty strong hills on my detour - though probably not the same.
