Stephen and I have both been "backpack" traveling for close to twenty years. When we started traveling, you had to carry all of your money in travelers cheques on your person for your entire journey or get it wired to you along the way. This was a pretty scary proposition if something happened or if you couldn't find a place to change your cheques, you were sol.
ATMs have made travel so much easier and safer. No longer are we carrying thousands of dollars on us at all times. You can find cash in just about every podunk town from N. Laos to W. Sumatra.
Communication with the outside world or even with your next stop was virtually impossibe or prohibitively expensive back in the old days. Mail was slow, if it ever actually reached its destination. The internet and cell phones have changed the travel dynamic enormously. Less frequently are travelers hanging out in hostels swapping war stories and travel tips because they are too busy face booking, blogging, skyping & sending texts to people across the world.
The major advantage of these technological advances ist he abundance of information available to the vigilant cyber-seeker. Some of our best travel tips have come from reading fellow travelers' blogs, which are more up to date than the most recent guide books out there.
One constant has been the Lonely Planet Guide Books, which are the bible for the backpacker set. A common site is to see a busload of weary travelers spill out the door while thumbing through a much worn LP guide.
For those not in the know, LP guidebooks have been around since the 70s when Tony & Maureen Whieeler traveled overland to SE Asia from Europe. These books have truly developed the backpacker travel through SE Asia (and the rest of the world) with the greatest hits nicely laid out with all logistics and details, budget accomodations and sites to see.
Even with the advent of blogs, travel advisor and travel chat boards, nothing tops "SE Asia on a Shoestring" for the sheer volume of information located in one large volume.
Another thing that hasn't changed is the traveler talk. Typical conversations begin with the requisite "Where are you from?", possibly some connection to that persons city or country or origin, a past visit there, a friend from their home, or the ability to speak their native language. You quickly move on to other required questions like "How long is your trip?" and "Where are you going/where have you been?".
Since most folks are on the greatest hits tour, the itineraries are strikingly similar, just varying in duration. As in every social group, there are ways to rank its members. Backpackers at the top of the spectrum are those traveling the longest. Round-the-world year long travelers often thumb their noses at those on mere vacations of three or four weeks.
Another technique to categorize and rank travelers is through budget. A new term has been coined in recent years - "flash packer", which is travelers willing to spend $15-$25/night v. "back packers" in the $4-$15 range. Back packers feel superiour to flash packers because they are not only getting more for their money, but they can endure rooms with no A/C, dorm rooms & communal squat toilets. They are more hardcore and traveling more 'local'.
Traveler talk quickly turns to the cost of things with lots of bragging about low costs paid for accomodations for street food & with incredulous at the exorbinant price someone else paid.
After almost 20 years of travel, we've found we are very much in the upper end of the age spectrum. We can officially be called flash packers as filthy rooms with no windows & communal cold water showers for $5 is no longer a great deal. Our aging bodies, stiff necks and over active noses require a bit more.
We also no longer look at 12-15 hour local bus rides with chickens, chain-smokers and people on the roof as an adventure. Now it is brutal and takes days to recover.
Nothing like some budget travel to remind you that you are no longer 25!
