Project

So, in my limited free time I have decided to start a project where I take a picture of one part of the sky in the same place at the same time every day. Then after X amount of time, I will put all the pictures together in order like 1 big picture, and hopefully post it on here. i hope it looks cool...I've always wanted to do something like this but have never know what to take the pictures of. So how long do you guys think I should do it for? I want to do some with snow to show the changing seasons.
