I really liked this fic. It has been one of the more imaginative and original time-travel fics I've seen, especially as Harry does not fall for Lily Evans, and manages to set things right during the first (and only) rise of Voldemort.
Too many Harry-goes-to-the-1970s fics use retreaded elements of Harry-needs-a-break-so-he-becomes-DADA-teacher and then half of them add the squick factor where he falls in love with Lily Evans.
Yours has been like a breath of fresh air and it's been making me wish more people wrote original time travel to the Marauder Era fic (Only EmySabath's "Time to Spare" gets close).
Good work :)
