4, or 5 years ago, I gassed up at Krupps in the evening. I moved my sled out of the way of the pumps to go in and pay. However I noticed a sled having trouble getting turned around on the ice. I put my helmet, and breath mask down on my sled, so as to give who ever a hand. As I returned, no more than 45 seconds later to get my helmet, and breath mask, I noticed my mask was not where I had put it behind the windshield. It was now behind my helmet, on the seat. I thought perhaps it had fell off, and some nice person had picked it up for me. No way! Turns out some A-- Hole, had quickly switched out masks with me! The one he left me was junk, and it stunk sooooo super bad from weed, I trashed canned it right there. No one seen anything? Good luck with that! I then went in, and payed for my gas, and told Jim what had taken place. It didn't surprise him, as he said you can't trust anyone it seems. I then had to ride back to the cabin to get my spare mask. The person who was wearing that junk mask could get screwed up from just breathing through it! A real A-- hole for sure! I only wish I would have seen him do it! There would have been a resolution he wasn't prepared for! With this, I really doubt the amount of sledders doing weed will change very much at all. As it appears they are doing pretty hard now.
