It is wise for any one to consider local condition and adjust his/her attitude with what would be advised by local travel service provider through their tour guide. A legal company will take responsibility to avoid annoyances for their guest and train their tour guide to keep the image of their company and the destination of travel. It would not be possible to do so for individual won arrangement travelers. For those own arrangement travelers often use guide book written by travel writer which might not be consistent or less consistent with changing fact of the field or might simply bias resources.

Lonely Planet Guide book which is known as the best of travel guide still has some informations less consistent with local conditions and fact, yet some information are very useful especially the very basic need for a traveler to understand in advance the local situation. For example is the remainder of the travelers to remain cautious on tradition, actual situation and conduct of the local people. It is realized that Indonesia has so many ethnic groups with some different ways of life and different orientation and added by variation in religion it is really like a jungle. We are lucky because Indonesian people are hospitable and easy to come along with any people or nation although bad experience of the past. But please also remember due to the religious influence some people might develop strange spirit, forgot his/her root as Malay and act as unrelated nation to Indonesia. This member of people are very small and only exist in Java, and South Sulawesi.

Lonely Planet travel guide writes some annoyances and danger that could happened to travelers without caution. For example trekking at Bukit Lawang, that unlicensed tour guide did not know about object they should explain to guests, only able to apply permit and feed orangutans which is against the regulation. A report was quoted of sex harassment to female travelers, specially during overnight in tent. So, travelers is advised o use the service of legal tour agent which employs licensed tour guide or representative in which responsibility is clear, and where the thinking that using illegal service is cheaper is not correct. Take care valuable belonging and use the service of the hotel, such as safety box, to avoid although not common the theft. In the city of Medan when one walking on busy street do not bring money too much until some one reveal it, and hand bag will not be a comfortable fashion to bring with during walking on the busy street. In case you would try a local cart of called becak, it is mandatory the rate be agreed in advance do not negotiate after or in the middle of the service. It is not nice to leave one becak to another in their all eyes to pursue rate negotiation. If you do not agree with one, it mean only one or for all, and get at other pool out of their eyes.

Theft is still a minor problem in Medan, even reported to have happened to local people that theft using motor bike, so he will not be caught up after steeling. Basically the hand bag will be the target whenever theft by chance passing by, and the belonging without watch up.

In Samosir island or Parapat town be sure that travelers use the service of hotel safety box for your valuables, and better choose higher category hotel to ensure the valuables be save and the trip be smooth. For those who wish to hire motor bike be sure 100% that the bike will be safe, if not small damage will be charged excessive repairement costs. Every where theft is a result of less care of the owner, so it will be wise to practice caution wherever and whenever we exist.
