How many miles would I end up going if I walk all around the border of Wisconsin (excluding islands)?

According to the website below,

Wisconsin's boundaries have a total length of:

1,379 mi (2,219 km)

It is not stated whether this includes the few islands apart of Wisconsin, Apostle Islands in Lake Superior, and Washington Island in Lake Michigan.

The total area of Wisconsin is 56,153 sq mi (145,436 sq km), of which 54,426 sq mi (140,963 sq km) is land and 1,727 sq mi is (4,473 sq km) inland water. The state extends 295 mi (475 km) E-W and 320 mi (515 km) N-S.

Wisconsin is bordered on the N by Lake Superior and the state of Michigan (with the northeastern boundary formed by the Menominee River); on the E by Lake Michigan; on the S by Illinois; and on the W by Iowa and Minnesota (with the line defined mainly by the Mississippi and St. Croix rivers).

At a very rough estimate, maybe 2,000 miles. This is because of the ragged nature of Wisconsin's lake borders
