path less taken
Yes, that's the one. The trouble lies in crossing Columbia when there are high traffic volumes. Portsmouth is a signalized intersection but then you have to ride across the grass or carry across the tracks. Fiske is not signalized so you get to risk your life instead.
I ride out there regularly and I've occassionally riden across the grass, but usually just carry the bike over the tracks.
Since the crossing is on Union Pacific land I wouldn't expect to see it fixed any time soon. Maybe the BES folks will pave the shortcut instead?
