No, I'm not turning my tickets to ashes.
However, before last week's event I had pre-purchased tickets for all NJ TRANSIT routes and PATCO on the side of caution, meaning I bought more than we needed just in case we had any late additions to the group, or somebody who hadn't claimed they needed a ticket actually did.
Right now, I have 2 PATCO tickets (good between all Philadelphia stations and City Hall or Broadway stations in Camden), 2 RiverLINE tickets, 3 NJ TRANSIT one-way commuter rail tickets between Trenton and Newark (good in either direction), 4 Newark City Subway tickets, and 4 Hudson-Bergen LRT tickets.
Since they can now be used at any time, there is no rush for me to use them. However, if anybody who did not make it to OTOL New Jersey Railfest 2006 wishes to someday re-create a segment of the fest, please let me know and I can join you. My tickets will already have been paid for, and I might even have some left over to sell to you!
