That's a toughy. I think you should walk at the end of the fall. Seems like that would make more people happy.

I would walk in the fall. Even if your cousin says she doesn't wanna walk, what if she changes here mind? you can't go back in time at that point. Can you walk twice? haha If you walk in fall and your cousin doesn't walk in spring, then you can walk then too.. hahaha.

its prpobably way to late to add in but i say fall

congrats! how's it feel to be a *real* adult?!
