Teddy Roosevelt loved Sagamore Hill and spent most of his life there, and since he is one of Matt's favorite presidents we toured his home a few weeks back and fell in love. The property surrounding his home is beautiful. We saw it covered in snow, and we were lucky enough to see it in bloom! There's a mile hiking trail which leads into this beautiful river, which makes for a lovely day-trip.
Also, it's dog friendly! Long Island has beautiful hikes and parks, so long as you look for them. The weather has been unreal, and it feels good to not need a big heavy coat! I finally caved and bought some Vans after Matt begged me for a while, and not only are they adorable but they're SO comfortable!
