What are somethings to do near Port Richey Florida?

I am from the Port Richey area, but am looking for some more things to do in the area. It can be in Clearwater and Tampa also, just in the area of Port Richey. I am having a friend visit for a few days and am looking for ideas. We already plan on going to Disney or Busch Gardens and Clearwater beach. Any other ideas would be very helpful thanks!
