Thanks to my several friends who gave advice regarding my trying to see the UP Challenger!
Especially to Don who clued me in to the route and where it would be tied up overnight, and to "Hoss". I left Dallas at 4:30 AM to see it, and it was well worthwhile. Chasing it at 60 MPH, I now understand the lure of mainline standard guage steam. And I also MUCH better know the difference between live and "Stuffed and Mounted" You won't get me far from narrow guage, but the Challenger was WELL worth the trip!
