Sunrise/sunset charts
When I'm traveling, I print out custom sunrise/sunset charts for my destination at sunrisesunset.com
I visit Wunderground star charts to get the lat/long coordinates for my destination, get a weather report. I use their sky charts as well, just for fun.
A few lat/long numbers I keep handy:
Salt Lake City, UT: 40.8 N 111.9 W GMT -7
Moab, UT: 38.6 N 109.5 W GMT -7
Springdale, UT: 37.2 N 113.0 W GMT -7
Jackson, WY: 43.5 N 110.8 W GMT -7
Auckland, NZ: 37.0 S 174.8 E GMT+12
