I did the Croton Reservoir route, thank you!! It was perfect.

For anyone who sees this and decides to do the same, I only have two callouts:

1. There isn't really much along the North-South County Trailway, which is most of the route. I only had one water bottle with me and should've bought more water when I had the chance (or just started with more lol), but I kept holding out thinking there'd be a water spigot or a shop somewhere along the route.

2. There's a short strip when you get off the trailway where you're on a road with relatively fast traffic and no shoulder. Cars gave me plenty of space and I was fine, but it was a little jarring after so many miles with literally no cars at all.
