Does anybody know a good contact, store, etc. for getting maps? Particularly international maps? I have found in the pst that generally good quality detailed area maps are available locally from geological survey/land control government services. However, in planning trips it is often best to get these maps before going. In a lot of countries these maps can be very hard to get outside the country (without going to the office...). Anybody have a company or somebody they use to get maps?
