Is there a mandatory rule to use snowboard leashes for CO resorts?

I haven't used a leash at a Colorado resort for around 10 yrs now.  It depends on the resort, and there is still a leash rule on the books.  I doubt you'll need to bring a leash though.

When I was out there a few weeks ago, Cooper got on to me for not having a leash.  Yes Cooper not Copper big mistake in going there

^^^Hahaha!  I can see Cooper mountain doing that.  Copper hasn't checked in years.  I'd stay away from Cooper...

Yea we wanted to do a half day and that is the cheapest half day ticket there is but it was a nice drive from denver

I used to wear my leash as a belt, just in case resorts hassled me or I found myself needing it.  Have just worn a real belt past year or two - no problems 

Even took off my stomp pad...although, that actually came in handy sometimes, but I've learned to deal with out it and shedding any weight these days helps
