Often, but not always.  I live in Duluth and work in Two Harbors and lately it's been a few cents cheaper in Duluth, actually.  The difference is no more than a nickel, typically, either way.  I generally fill up in Two Harbors, though, because I buy the THHS Band Card which gives me 3¢ off a gallon year round.

By the way, if you want good pie while you are traveling the north shore, I suggest Rustic Inn pie over Betty's.  Just don't tell anyone I told you.

Sorry to continue the off-topic discussion, but had to add this: the food at Nokomis and New Scenic cafe some of the best in the state, let alone the North Shore.

You should venture further up the North Shore for more terrific pie at Chez Jude in Grand Marais!

I love pie.

(Though I do consider myself an agoraphobe ... but that's why I live here)

Seriously though ... enjoy it! The SHT is a gem within a gem within a gem, very nearly adjacent to a couple of other gems. Hell, the entirety of Northern Minnesota is one big emerald and sapphire necklace (green and blue ... get it?) ... and it cuts right through Split Rock S.P., as well as every other State Park on the North Shore ... so if youare* a bit agoraphobic like me and get a little weary of the crowds ... you might consider taking a short day hike up a spur trail and onto one of the prettiest trails I've ever set foot on. I've logged in over 250 miles on the Soup in the last 10 years and hiked every section between Crosby-Manitou and Castle Danger.

There's also another gem hanging out about 20 miles due east off Grand Portage, too ... it's about 50 miles long and about as close to being in the backcountry as you're gonna get on a tank of gas.

I know I'm a little late for a National Trails Day plug, but hey ... every day should be National Trails Day!
