You will meet a lot of people while touring. It is easy to make a connection with a fellow traveller and folks you meet during the trip. A good way to remember them is to have a contact card. These have two uses. One card is for me to write their info on and what circumstances/location I met them. A second card is given to them with a personal note based on the encounter.
These come from VistaPrint and I just used a generic stock photo. A box of 1000 was $14 dollars if I recall. Using a Google Voice number is an easy way to control interuptions. Calls are logged and voice mails are saved for me to review when I have internet. I can also patch calls through to my “real” cell number if I need to.
