Blaster, I would likely help if you let folks know where abouts the folks needing a swap are. Also, I think there will be an opportunity to swap during the check-in before the Ride...but you'd likely have to confirm that with the folks at the Ride office.
I have a medium would love to trade for a small. I work in Calgary. I don't have it with me today, but I can meet you Thursday to make the trade if that works.
Have a large but need to trade up for an XL. It's fine through the chest, but damn thing is cutting off the blood flow in the arms and I like it a bit looser through the mid section. Anyone that has an XL to trade for a large, let me know. In downtown Calgary and can meet Thursday or Friday, or we can hook-up on Saturday morning.
