Version 1.6.0 (12/20/08)
Minor updates to trail 442 in Alger County, 109 in Houghton County, 16 in Iron, 2 in Schoolcraft and trail 2 in Mackinac County. Thanks to Rob E for info.

Added National Forest Roads for all National Forest in Michigan based on current Motor Vehicle Use Maps released by the USFS. Note Manistee National Forest has not been finalized at time of release.

Version 1.2.3 (2/19/08)
Added old-style fuel station points to map to better show fuel stations on the map while also keeping the "new" style to better enable searching (points are now duplicated in map). This enables viewing on Nuvi/Zumo units which do not have ability to show all POI regardless of zoom unlike other Garmin models.
Added misc POI for food/fuel/other (approx 30 items).
Updated Trails 1, 3, 12, 120, 122, 124 from White Pine through Keweenaw.
Thanks to Gary R. & Craig P. for information and tracks for these corrections.
Updated Trails 59, 590, 591 near Niles.

Updated Trail 4 near Waters (where Trail 4 & Trail 7 Intersect).
Thanks to Rob E. for information & tracks for these corrections.

Added hundreds of points of interest (POI). Includes Commercial Members of the Michigan Snowmobile Association - members have "(MSA)" appended to end of name. POI added include gas, food, lodging, dealers and other (not all POI have had coordinates verified, expect some location discrepancy).
Corrected search function for POI such as fuel, food and lodging so that "find" within the GPS will work as expected.
Modified zoom levels so that trails now show at extended views (was 3 miles, now is 150+ miles).
Changed county and forest roads to show only at lower zoom levels, improves map display performance.
Corrected name for Trail 8 segment, was labeled Trail 2 from Shingleton to Wetmore.
