Leave it up to my friends at Walking Adventures to think of what I should have been using all along! I fly with bags that must be under 50 pounds. Silly me. I held the bag and stood on the scale, then deducted my weight and hoped for the best. It was unweildy to put it mildly. Now I find out that they have these simple luggage scales that will give me the information I need!
And now I'll know exactly how many souvenirs I can buy on my trip!
