Heh, this was a most interesting chapter. It appears that Harry did go backtime at some point and you have to wonder just what affects his knowledge of the future had. 'Twas quite interesting to see the Dursleys actually providing some most interesting clues to matters. I admit to wondering what was watching him in Remembrance Park and I can't help but wonder if the goblins were sealed underground by that explosion but are still monitoring "topside" for wizards and/or traces of magic? 'Twill be very interesting to see what you've got set up as well as what "adventures" Harry has before returning to his home time.
BTW, I'll agree with Wonderbee31 that the bit with the Corvette was a touch tie-in with the movie.
Author's response
Believe it or not, the bit with the corvette was actually an homage to a stunt a friend of mine pulled back in college in the early 1990's. He got clocked doing around 120 mph on the interstate in his dads 65 'vette. When he was pulled over for the tickets, he pulled it a little to far off the road and it slid into a ditch damaging the car in such a way that it couldn't be driven until the suspension was repaired. I didn't see the trailer for the Movie until after I had written that part.
Chunks of this story are already roughed out and as I get to the chapters I want them in, I insert and polish to fit as necessary.
Goblins are floating around, but at the moment, just like the rest of the wizarding world, aren't going to be interacting with Harry.
Have no fear though, all will be revealed in later chapters.
