Pete, have you seen my 50K and 100K stickers? Their design was based on a sticker that someone (can't remember who [one of the signs of my aging process is that I can't remember names]) brought to our first rally in Spearfish. His were different from mine in not having the mileage numbers in the middle.
I'm having a big internal debate about whether or not to make 150K stickers. Rust-in-Peace and Woodaddict are streaking toward 150,000 miles on their NTs and I'm creeping in that direction. I'm still probably 2 years or more away from reaching that milestone.
Have you found a reasonably cheap place to get stickers made? I paid a bit over $25 for 72 of the 50K stickers, IIRC, but the 100K stickers cost me about $40 for 50. I'm guessing that during my lifetime, at the rate we're going, I'll never need more than 5 or 6 of the 100K stickers. I want to get them for Rust-in-Peace and Woodaddict (and for me!), but don't feel like spending $40 for three of us!
BTW, I like your idea, even if I'm not sure that I want to acknowledge the reality that so many of us are old guys. There are a few younger guys and I don't think any of the gals riding NTs are old.
We'll kick the idea around at Spearfish -- if you don't bring finished stickers with you. See you there!
