+1 here. I haven't gotten out on my bike too much or had a chance to get "up north" (michigans northern lower pennisula) but I agree, the smell of air, water, dirt, seeing stuff start to grow, etc. Is great.
We try to go for walks with our 2.66yr old girl all the time. She is so bright and appreciates when you point out a red wing blackbird or flower.
We live in a little downtown with mature trees and such. Other than teach safe street crossings, it is a nice environment for her-the reason we moved.
