Actually, I don’t necessarily advocate sharpshooting. There’s a lot of ways to do this.
*Defeat the Hartigan Gang before the stagecoach ever becomes an issue (requires high Gunfighting skill, or Carson and Schmidt).
*Betray the stagecoach to Hartigan, if you’re a bit of a rattlesnake.
*Not get involved.
*Have Schmidt along, or a high Survival skill, and head across the sand.
*Have a high Engineering skill and head across the rocks.
*Have a high Gunfighting and Sharpshooting and clear the road.
*Have a high Sharpshooting skill, or a good Riding skill and either Gunfighting or Explosives, and put out the match.
Once you’re past Hartigan’s roadblock, put the horses to a gallop and ride hell-for-leather. The Hartigan Gang will disperse once you reach Utah. Okay, you can fight them with the stagecoach, but I never do that. If I’m going to fight the Hartigan Gang, I usually fight them at the canyon. If you do decide to fight the Hartigans on the stagecoach run, remember that Carson is the best rifleman in Lander County, and have him along.
