Without showing a spoiler, I feel like there should be a palindrome in the 3rd to last paragraph. A cartographical product is mentioned in the 2nd to last paragraph that is not mentioned in the list.

Also, I think there is a typo in the part about how cool Ed's car is (its audio properties, specifically).

Did anyone else catch those? I can get 50 by fixing the typo, and I think 51 could be gotten by modifying the list of Ed's tools. I'll have to go back and look for #52...
