Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
Start early — leave by 6-7 AM to arrive at a reasonable hour.

Wine and water define the Finger Lakes, a region of New York state south of Lake Ontario. Eleven elegantly elongated bodies of water arrayed across 80 mi (130 km) of rolling countryside have produced one of the top wine regions in the country, the East Coast answer to California's Napa Valley. While the wineries that dot the slopes above the Finger Lakes—over a hundred of them—are a major draw, visitors also enjoy the region's many waterways, from the Finger Lakes themselves and Lake Ontario, to the mighty Genesee River and the historic Erie Canal. In the fall, leaf-peepers turn out in force, and wintertime sees skiers heading to the area's slopes. After a day enjoying the sights and tastes of the Finger Lakes, head to Rochester, the state's third-largest city, for urban amenities and nightlife, or enjoy the college-town atmosphere of Ithaca overlooking Cayuga's waters.
