Another idea to save money on your souvenir purchases when you travel is to purchase garden seeds which are local to the region. These make great gifts to give to people, or keep for yourself.
When you try to grow plants and trees that you often look at through your vacation photos, it is returning to the trip experience once again. These are simple and easy to pack in your bags to take home with you (not extra weight).
Even your friends will have fun trying to grow these unique, and sometimes exotic plants from other regions. Of course, be sure to ask about any guidelines or procedures about buying these. Most procedures are geared to actual growing plants, and not seeds.
Have fun on your vacations! And, turn down the street that is not on your plan, to make a pleasant discovery. The Fun Tour Guru.
