I drove from Virginia to see the eclipse at Niagara Falls. I was standing at Terrapin point and got a glimpse of totality through the clouds for about 20 seconds. Totally worth the trip!
I didn't buy them, but if I had, I would probably keep them forever as a memento of the occasion. They should also be good for another eclipse if I should live long enough to see one. Maybe my nieces grandchildren would be able to sell them on the future version of eBay.
I plan to keep mine for the memory (and hopefully re-use for sun spots!) but very cool that they are being recycled. No totality for me but I used my eye glasses on phone camera and got some nice crescent pictures.
