People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.
My preference depends on the purpose of the travel. On a summer vacation I travel to refresh myself and to see the countryside. When I use my feet and walk on a grass covered path along a river or among the hills I feel detached from the noise of the city and closer to the nature. And when I travel on foot I get more freedom. I can plan my own schedule. I can choose my own route. I can stop where I like. And I can see things and people that I might miss if I travel on a train or on a bus. net
When faster and more convenient ways for travel are becoming available, I still favor using my own feet. I get much pleasure from it. People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.
