If you can make out the dotted line, that was our route last year on this trip. It's a 360 mile or so trip for the day depending on were you start out. It's about 110 to the State line start and it was 258 from the start of the offroading to the return to S.L. via Brigham City. The total off road was around 180 or so. We didn't need our extra gas last year during the offroad section, but I will still bring an extra 5 gallons just in case. There is a gas station at the state line start, and of course in Brigham City at the end. Like I said, it's a long day. We need to start out from Salt Lake by 7 AM and we should be back by 8 or 9 pm. That's counting exploration stops and general unplanned fun. We did it in that time last year with stops at 4 or 5 ghost towns, exploration, and an unfortunate tire change due to an errant rail spike.
