I got an infraction ticket (merrr, shoplifting..) in Arcata with the court date mid-May (which, when I got the ticket, was about a month away). There was no way I was sticking around for that crap, but I like Humboldt County and didn't want to have any warrants. So I just went down to the court a couple days after getting the ticket and told 'em I was leaving really soon, the woman at the desk was really cool, you might have to make some kind of "I have to leave town" emergency up if you happen upon a meaner receptionist. Actually I ended up having to call the courts a few times (once 'cause I had to notify them of my mailing address, then a few times after that because they were all like "I don't know you might have to appear" and I was all like "Um I'm in Chicago") but after a few calls they finally sent the damn ticket to me in New York. It was annoying (as is paying a ticket) but personally it's worth it to not have warrants.
If you're planning on going home I'd suggest taking care of it now/while you're on the road (anytime before the date really), for minor shit like that they won't put out a warrant but it'll be a bench warrant, and if you get cited/arrested/stopped for anything else when they run your name they'll have a good reason to take you in.
But like, do whatever you want. And have fun on yer trip!
