Right from my childhood I have been regularly traveling from Margao to Udupi/Mangalore by road. Tagging along with my grandfather on his visits, or making a quick vacation of my father's business trips or just going to visit my maternal grandparents and other friends and relatives in the area. And for the last few years, to visit my in-laws.
The road from Goa to Mangalore is along NH-17 - a coastal route along India's west coast. It crosses the western ghats, passes through scenic hills and is adorned with little villages and paddy fields and has a brief stretch at Marvanthe of about 5 kms. right by the Arabian Sea, which suddenly gives way to the maddening traffic on the Kundapura-Mangalore segment. And all along of course, you are never lonely - there are people, cattle, parked trucks and farming machinery of all shapes and sizes. More recently - for the last 12 years or so - the Konkan Railway line that runs parallel to NH17 in many places also keeps you company on your drive.
As the roads and infrastructure improved and so did the quality of cars, the 300+ kms. journey became a half-day affair. Start early right after breakfast to reach by lunch time, or leave right after lunch to reach in time for dinner. Each trip to Udupi would be about 3-4 days, filled with fleeting visits to meet cousins, aunts, uncles and friends and of course, sumptuous meals at every house we visited. Feeding your guests like they live in a drought-hit area is of course, one of the cornerstones of Indian hospitality.
