FWIW-at this point I have confirmation and links that Heather got gas at the Kangaroo Express at 1929 Joe White Ave/10th Ave N. This is the one near Seaboard, further away from the 17 bypass. I have pictures that show it has a payphone that has all it's parts (doesn't mean it works). I do NOT have confirmation of the address of the pay phone SM called from around 2:29 on Dec 18th. I only know that one was on 10th ave N.
Okay thanks Ghostwheel. That's the first time I have seen the receipt addy confirmed by MSM as being the Seaboard/10th ave location.
At any rate if sm used that phone at Seaboard/10th ave or the one at 17 bypass/10th it seems that is somewhat far from his home? It's a good 11 miles from 10th ave N to his house. It is close to the Tilted Kilt, though and one of the IE locations at Broadway at the Beach.
