Now that you mention it, I do remember the "Middle Marker Transition". Can't remember how often I might have used it vs. Goleta-Lobster, though.
I don't have SBA approach plates from that era, but looking at a 1968 VFR chart, the radial (~105°?) from Gaviota to the old Channel intersection on V27 would pass right over the SBA MM. That must have been how the MM transition worked -- Channel via GVO R-105(?) to MM, then outbound on the localizer to Halibut and the procedure turn. An ADF would have been helpful, but I didn't have one.
Looks like V27 was realigned a few degrees further south, too (FIM R-253 then, R-250 now), so GOLET is a couple miles further offshore than was the old Goleta intersection.

But KWANG has been moved a few miles east on V27 from where Channel was. So the R-099 from GVO to KWANG passes just east of the airport, creating the VOR RWY 25 final approach course. I never understood the change before; now it makes sense. Thanks for the memory jogger.
