Thanks, Throck! That's a good point. I usually forget cleaning solution since I normally carryon all my photo equipment. I usually use a rocketblower out there and just avoid cleaning lenses thoroughly until I get home from the trip.
That's probably exactly what I'll do. Those three lenses were really my intended final kit. However, the 24-70 and 70-200 are lenses I got recently so I've never traveled with them before. They are definitely larger lenses that also carry a higher replacement cost if I were to lose or damage them on the trip. I guess I was looking for people to say "Don't walk around another country with a 70-200 strapped around your neck you're just asking to be mugged." I like these two lenses for local work where there's less travel and more safety involved, but abroad I dunno (it's just Cancun, Mexico though). I actually just realized that since I got the D600 for Christmas I haven't even traveled with it yet!
