Few realize that we have hills in the Florida panhandle. They aren't large hills, but there are a lot of rollers and short grades that are fairly steep.
I haven't ridden technical trails since before there were "mountain bikes." (I grew up in western NY and of course back then we just had bikes that we outfitted for the purpose.) At my age I wouldn't consider it now but I'm also sure that if I was already doing it there is no way I'd consider stopping. You stick with what's comfortable and for me that's now the road. I do have the good fortune of endless miles of very low traffic country roads at my doorstep.
