Ideas for a fun day for a 6 year old

Bianca42

We had a Mike's Fun Day last month and went to the park, to see Cars2 and picked out all his school supplies.  We have another one schedule for next week.  He gets to pick what we do, but I'm looking for any ideas that would be more appealing than Chuck-E-Cheese.  (I really don't want to go there.)  So far I've got:

• Buffalo Zoo
• Niagara Aquarium

 I'll be dropping Alex off at daycare and picking him up again, so I can't go too far away.  Any other ideas?
