Does anyone know when Lakeside Park usually opens for the season?

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.

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.
