My main complaint about the Hudson River Greenway is that it is not immediately next to the river, so for the most part you can't really have any view. All you see is fellow cyclists. Once or twice, it's fine. But after a number of times riding on the same path, I feel like I am just riding on a stationery bike in a gym, with the added disadvantage (in the summer) of being baked under the sun, especially in the early afternoon.
