The calendar on thier website begins in July. I hoped they would open before that. I emailed Lakeside but didn't get a response. I hoped someone else knew because I'm planning a trip to Denver that I would like to do during May.
My band "The Cedar Kings". "Ordinary Day" a trip report in song.

they usually start operating weekends in late April. Rather than e-mailing them though I would suggest calling them. They're much more reliable when answering the phone.
