Took me a while but I get it now. Big motor running to pull riggers and electric on front running reverse to slow you down. I would just pull a sock rather than mess with that and wear stuff out
Dave told me yesterday that he was heading to Whitehorse
My daughter and her children and dog got out on a flight today
Her husband is doing the drive.
Sorry to inject this into Dave's thread but I fished with him a couple times.
