Saddest first car story ever. Bummer.
That sliding (or spinning) backwards is the most helpless feeling. Had it a few times......but never ended quite that badly.
Unless you had a Leupold, that rifle was likely knocked off zero, anyway.
83 mustang! Grey, chess little hatchback with a gutless v6 and auto. Bought it myself at age 15 for $2300 in about 88. I totaled it hunting deer. Almost made it too the top of an icy mountain road before it slid backwards down it dropped off about a 10 foot bank and landed upside down in a mountain creek.
Saw some huge bucks on the walk out but needed to get off the mountain and stop some bleeding so we didn't try to get on the deer.
