Design by christianpoetoe with the mountains is probably my favorite right now. I like the mountains, they resemble the Flatirons mountains. The font is good too, and the green is nice. I would like to see the mountains look just a bit more rugged though, perhaps a bit more pointed instead of rounded, and take out the second color gray. Keep in mind I will need this logo to look good both in color, and when just a white decal. Thanks
