First after leaving the boat launch at Chena pump i went up the Chena to Chena small track road where everyone left the river. Just one old track up river from there.
Down the Chena river again with one small open spot below the mouth, no problem, smooth and good till you get to Chena ridge bluff, trail swings up river away from bluff about quarter mile and cross ice flow. Across some gravel toward Howard Luke's.
At the next bluff stayed to the river and toward Salchaket slough and onto the long straight away towards mouth of rosie creek within a mile there was open lead from bank to bank, turn around back tracked to the first slough past Salchaket in that slough and if you stay to the right will bring you on out on the river below the open lead. Went down river to past the cabin and at the mouth of Rosie creek turn around there was a track ahead but lots of flow ice. Went into the swamps on the air boat trail.
Ran airboat trails so dirt was not a problem some grass spots and swamps gas holes in the ice were something to watch for but not a big deal.
I have some inside ski lift so cornering a 90 mile an hour was a bigger problem.

If you can't fix it with a hammer, you've got an electrical problem.
