In September of 1981, my brother and I decided to take a road trip to see some friends out west and go to Glacier National Park. He was leaving for college (SIU) and I was going into the Air Force in a couple weeks and wanted one last trip before we couldn't anymore.
We took the family car, a diesel Olds 88, since our own cars wouldn't make it for this trip. We packed up, drained our bank accounts, and headed west on I-80 from home (far northern Illinois). We visited friends at U-Iowa in Iowa City (2 days, lots of parties), U-Sioux Falls in South Dakota (2 days, lots of parties), U-Wyoming in Cheyenne (2 days, lots of parties) and finally U-Montana in Helena (2 days, lots of parties). With a 1 day drive between each location, we were already 12 days into our 2 week trip and close to our final destination.
Running low on time (and money) but we were determined to get to Glacier, so we left Helena headed for Missoula. Got there and found out the route north to the Park had gotten a foot of snow and only 4x4s were being allowed through. So, we decided that was not going to happen and turned south for Yellowstone Park. Made it to the north entrance and it had just closed down for the day only letting people in unless they had a reservation to stay. Disappointed, we headed to Bozeman for the night. Day 13 was gone and had 1 day left to drive home.
We got a few hours of sleep in the car and left Bozeman at about 2:00 am. Reminder, the national speed limit at the time was 55 mph, but the family Olds had a little over 700 miles of driving range on 1 tank of fuel. Short story: 1350 miles and 21 hours later we made it back home at about 12:00 midnight - after driving straight thru with a fuel stop in Mitchell South Dakota and switching drivers -at speed- by jumping into the driver's seat from the back seat with the cruise control set at 70ish mph.
So our 14 day and 2700+ mile adventure ended with lots of good memories of parties and friends, but no tee shirt from Glacier National Park.

That morning I reported to the Air Force Recruiter to leave for boot camp and my brother piled his stuff in his car for the 400 mile, 6+ hour drive to Carbondale. Was the last trip we took together.
