If you enlarge the overhead map above, there is a postage-stamp sized lot (tiny gray-white box) across the street from the turn-off to Gate 8. There are usually spaces there - but all bets are off on or around Induction Day. Park there, cross street, walk on sidewalk to Gate 8, keep walking, boathouse comes up after baseball fields on your right.
Go over the bridge, Worden parade field is on your right, Alumni Hall on your left.
You may want to recon that lot. I don’t know what signage may be posted there. I thin it is overflow parking for residents of the military housing on the hill behind it.
