Swung by the Idaho parks & rec office and purchased my invasive species sticker, which I then plastered onto my sailboard. Now we'll see if it sticks. They were plenty busy, but it was a breeze picking up the $5 sticker (for non-motorized craft; Idaho-registered boats are $10, those registered elsewhere are $20). There was no wait. Phones were ringing off the hook, and parks workers were advising folks that if they order their stickers on the Internet and keep their receipts, they can show those to the cops over the holiday weekend and they won't get a ticket, even if they haven't gotten their stickers yet. Here's a link to the full info about Idaho's new boat-sticker program to raise money to fight invasive species, including keeping fast-spreading quagga and zebra mussels out of the state.
