Every year, scores of boaters travel the 6,000-mile route around the Eastern United States.

The Great Loop has been called the last great adventure in North America, a 6,000-mile journey from the Mississippi River to the Gulf Intracoastal Waterways, around Florida and then up the Atlantic coast, across the Erie Canal, and through the Great Lakes. In 2022, only 227 boats returned to their point of origin, “crossing their wake” and earning the privilege of flying the gold Great Loop burgee (flag). Most “Loopers,” traveling in boats at least 30 feet long, took about a year to complete the route. Omaha Nebraska’s Mike Straub completed the loop in just 91 days. He did the whole thing on a Sea-Doo jet ski.

I think retracing the Lewis and Clark expedition would be a great adventure.

Anyone know how to interpret a 'perimeter acre'?

Perimeter Acres

133,489.06

from: https://www.kptv.com/wildfires/

perimeter	perimeter acres
1.14	179.5
3.86	226.09
4.4	701
50.82	18432.12
147.43	84364.39

Plugging in the numbers from the above fires, I get an R² of 1.000 for a quadratic function: y = 2.1122x² +264.07x -474.36

where y is 'perimeter acres' and x is the perimeter, in miles.

A perimeter acre is probably defined as
$$\frac{\text{length of the wildfire's perimeter}}{\text{area of wildfire}}.$$
