The organization holds annual three-day reunion/shows the third three-day weekend in August, hosting them on its 25-acre show grounds which is located adjacent to the north side of Itasca State Park on MN # 200.

More than two dozen rustic-framed buildings can be found in a shady, park-like area on the grounds, and these house a sizable auditorium, logging museum, kitchen, blacksmith shop, engines, models and toy displays, hot-air engine displays, and other activities.

Another area adjacent to this site houses the historic Itasca Park sawmill, the equally historic A J Levorsen sawmill engine, and the Roy Hemmerich Logging Memorial.

LIRPF reunion activities include:  Grain Threshing, Log Handling, Lumber Sawing and Planing, Lath and Shingle making, Activities (including Lefse making and Rug Weaving), Working Gas Engines and Machinery, An Operating Scale-model Railroad, Corn-husking/Shredding, and Grinding.

The greatest display of hot-air engines, in principles, sizes, styles, and diversity of design and application, and one that is un-equaled and un-matched ANYWHERE, is found at the Hot-air Collector’s Reunion, a part of the LIRPF show.
