So, I'm writing a post-apocalyptic/zombie novel set in the near future... yada yada yada. Anyways, the 2 main characters will be travelling from the East Coast (NYC) toward the West Coast (through Vegas, into Los Angeles and up toward Seattle). Here is my issue: although my plan is for the characters to head West, I am having an unusually difficult time coming up with a genuine reason why they are heading West in the first place. I've tried to come up with a few different ideas, but they all just seem like crap. So now I'm turning to you guys/girls in the RPGuild community. What would be a good, genuine idea explaining why two characters - in a post-apocalyptic, zombie infested America - head to the West Coast? Please help!
