Found him...
Do a Google on "BC-7 & school road Harrison mills"
https://www.google.com/maps/place/BC...!4d-121.945324 (Hint: Lougheed Hwy = BC-7")
it looks like Harry followed the Google car eastbound along Lougheed Hwy from before the Harrison Bay store (it's hard to make out how much before that Harry comes into the picture due to the distance behind the car he started at (yes, a CMP overtaking modern traffic) and the curves in the road) to School Rd and then the car either turned off or pulled over to let him and the logging truck pass.
