What's in My Round-the-World Travel Bag? (Part 5 -- Toiletries)
The TSA's ridiculous limits on liquids and gels have had at least one beneficial side effect: you're forced not to overpack heavy liquid-based toiletries that you don't really need. You can buy just about anything anywhere; it's not like people in China don't brush their teeth. Plus, it turns out that there's good alternatives out there for things like shaving cream. On short trips, it makes sense to pack your toiletries in advance; if you're going to be spending months between airline flights, bring the bare minimum and plan on shopping locally.
