@George,
Ive discovered RAil Trails. Theres a national organization that has them documented and they publish maps and activities (besides just the walking)
Ive gotten into biker trails cause you can cover distances so you can see stuff (We like flower preserves where the hummingbirds hang out and, if you wear a RED hat, they will buzz you like youre a flower)
We always carry some syrupy stuff and when the red hat thing gets boring, we put some syrup on our hands and theyll alight and slop up the sugar syrup from anything like a eye dropper to a thimble.
Runnig is ok but seeing and interacting wth nature , thatsa bomb.
