Ahh, A bit late, Bit I use Round weights .Like on a Work out bench bar 10 lbs, And zip tie them to the bottom of the EZ Up .
No salt damage, But, I have been at Bonneville 2014, 2016 & 2016 and have not been in the wind storm you see on videos.
But we leave our EZ Up , In the up position, But we take off the cover , So we leave the Skeleton frame up only.
If you bring a pet, Bring a Motorhome. . Otherwise, No , Its too Harsh, The salt is every where, I wear contacs and I can feel it in my eyes
