The great escape!

[Mamabearemma]

Hello there,
My nine month old son seems to be eager to make the great escape every time I open my front door, he speedily wheels his little red car walker towards the exit and when I close the door I feel so bad about not knowing where I should take him for a fun day out.
We go on walks and to the swings but I feel like this isn't enough. Suggestions?
