I just finished "EKAT" recently as well. If you love the writing, then pick up some Hunter S. Thompson. HST and Wolfe were primary experimenters in what was called "New Journalism", or what Thompson called "Gonzo Journalism". You'll remember Wolfe mentions HST a few times in "EKAT".
HST's first book, "Hell's Angels", did for the Angels what "EKAT" did for Kesey and the Pranksters. It was published before "EKAT" and, I think, influenced Wolfe.
You'll definitely notice a kindred spirit between the two, even though Wolfe and Thompson have intrinsically unique voices.
