I fly Arvada too- great site. Only busy in the mornings on nice weekends, evenings are way more chill. Rules are pretty well adhered to- almost every time I fly Phil (safety officer) gently reminds me that fast close passes (never this side of centerline

) make people uncomfortable... [

] Not to mention the mandatory $200 runway fee...
The Grass runway is... in progress- right now its more like small pebbles, sprouting grass, and prarie dog holes... Fighting an uphill battle there. Dave has his work cut out for him.
I have heard that Chatfield does get pretty crazy- but there are alot more accomplished 3-D pilots there FWIW. I will check it out when my Funtana gets finished.
Hehe- there are a few other flying attractions in the area- more like surfing though...
