When heat wraps itself around your shoulders like an electric blanket with static cling, there's only one thing to do: Look for cold water.

You'll find it tubing on a spring-fed river, such as the South Branch of the Root River, which takes a short cut through Mystery Caverns and heads toward Lanesboro chilled to 48 degrees.

On Minnesota's North Shore, plop yourself into one of the Baptism River's potholes and let the cool waters swirl around you. Or go whitewater rafting — a fast cool-down is guaranteed.

To children, the breakwall of Grand Marais' harbor is one big amusement park.

I watched in fascination as a barefoot 3-year-old in diapers zoomed from one jagged outcropping to another, scrambling up a chest-high cleft in the rock to follow her 6-year-old sister along a lichen-covered ridge.

"They climb anything and everything," their mother said, smiling.

There's nothing like finding the perfect campsite.

I look for them wherever I go, and when I was at Northern Highland-American Legion State Forest, one of the most popular campgrounds in Wisconsin, I found it: Campsite 435.

It's framed but not enclosed by trees, has a lovely view of Crystal Lake and is on the edge of its sand beach. It's near the shower house and not too close to latrines, easy to reach but not heavily trafficked and off a paved bicycle trail to nearby towns.

Over the Fourth of July holiday, every town worth its salt holds a celebration.

There are band concerts, parades with antique cars and cute kids dressed in red, white and blue: It's all good.

But it's an especially good time to travel along the border of the United States and Canada, which celebrates Canada Day on July 1.

In this region, you don't need oceans for a beach vacation.

We have thousands of lakes, plus inland seas on shoreline that often is called the Fourth Coast. Lake Michigan's shores are a veritable Riviera, and even rocky Superior has some noteworthy stretches of sand.

You could throw a dart at the map and come up with a good beach. Or you could take a cue from names of state parks — Point Beach and Harrington Beach in Wisconsin, McCarthy Beach in Minnesota, Orchard Beach in Michigan.

On a summer day in Holland, Mich., all roads lead to the beach.

When we were there one June, people streamed toward this broad swath of sand until the sun fell low on the horizon, making the fire-engine-red harbor beacon glow like an ember. They ate ice cream, they strolled on the breakwall, they took a last dip in Lake Michigan.

But at 10 p.m. sharp, a police cruiser started flashing its red lights to shepherd everyone out of the park.
