Cost of gas stopping a trip...
Ok... we're talking a two month trip.
You're concerned about the cost of gas for that trip.
I can see that.
My question is this: What are all your other expenses? What is the TOTAL cost of this trip?
Gas - $2000
Food - ??? (cooking yourself or restaurants?)
Campground fees - ???
Entertainment - ??? (in case you want to catch a movie on a rainy day, park admission etc)
Shopping - ??? (I can't be the only one who brings home junk)
My point is this: You're not talking about a $600 out of $2000 difference. You're talking about a $600 out of $??? (likely more like $4000-$5000 - I dunno). It's a matter of scale. The cost of the trip is more than just gas - a lot more.
If the money is tight - it's tight and there's not a lot to be done about that (short of garage sales and scrimping). Alaska's a beautiful place though, there's no denying that.
Course - at $2k - Airplanes and Cruise ships are really cushy.
That may be blasphemy on this site - but it's true. Not every trip has to be a camping trip after all.
