Strong congratulations on getting Sheridan in these conditions, Jay. Kudos!!
Did you see the fiasco a little further up the road toward Leavick? I wondered about that truck that was stuck, with a couple more cars past it, and how they were going to get out. On our way back out we saw the tow truck. The tow truck had a flat. Poor guy was definitely having a bad day. They got it fixed, though, and everyone got out ok.
I did see a Jeep Wagoneer that was stuck. The tow truck was just starting to try and get him out when I went by him (about 2PM) Didn't see any others trying to get by it. I parked back where most people did, I think - mine was the FJ with Vietnam Vet tags. I learned a long time ago that the extra half mile you drive can add hours to your exit. Had to spend the night in my truck once because someone abandoned their vehicle blocking the exit. Won't make that mistake again.
PS - I just emailed you a few pics I took of Sherman while I was on Sheridan. Feel free to use them in any trip report you write and I don't need any credit. Actually, next you your pics, I don't want any credit!!!
