You saw me with a fully-loaded LHT a week ago.
That storm was epic in a hammock, and the LHT frame was just fine pounding out 91.5 miles the next day to just past Osakis where we camped, all into that 20+ mph wind.
Oh man, yeah, I remember. I told my boss I had put two guys on bikes in site B-5, and he said nobody came up to him with problems in the morning. I patrolled through the park by truck as the storm was ending, but nobody flagged me down. We had a few limbs down at both locations, nothing major, no property damage or injuries.
He also told me, in the future it's okay to put touring cyclists in the lake picnic area, so next time, whether it's you or anyone else, that's what I'll do. At Sand Dunes I would put you in one of the Pineview group sites.
Glad you had a good trip. Hope it was somewhat cooler on Sunday, and that you and your son-in-law got some quality time together.
