Wagon Party 3Oregon Trail heading west (2) - lendunistus, dsjstr
With the votes to go west, the party continued along the Oregon Trail to Oregon City. Around June 9, they reached Independence Rock; nine days later, they reached the "Parting of the Ways". Given that the party had plenty of food, they took the Sublette Cutoff to shave a few days from the journey, traveling through an arid region of what is now Idaho, Utah, and Wyoming to Fort Hall. After refreshing their supplies, they continued along the Snake River for several days. At the Snake River crossing, the wagon tipped as it was floated across, resulting in the loss of some supplies but fortunately no injuries. Deep in the Rocky Mountains, Sirius9121 caught "mountain fever".

The guidebook was not of much help.

The party opted to control Sirius9121's fever and continue traveling. Outside of Fort Boise, the wagon attempted its final Snake River crossing and tipped again, resulting in some loss of supplies. With all of the losses, the team decided to take the road to Fort Walla Walla instead of speeding to the Dalles. Along the way, they ran into an abandoned wagon with a guitar and fishing net, which they grabbed. At the fort, they purchased 230 pounds of food, which would last long enough and then some to reach their destination.
On September 2, they reached the Dalles, the final leg of the journey.

What did the party do?
Barlow Toll RoadRaft down the Columbia RiverPay someone to raft you ($80)This is endgame. No matter what you choose, you will make it to Oregon City unless there's a massive accident on either the toll road or the river, which is somewhat unlikely. Each of the other two parties took different options, so there isn't much new here unless you want to see how I fare with your party when rafting down the river.
Either way, good luck! Once you decide (or someone else decides for you), I'll post and close out the Let's Play.
