You're a dog lover obviously. Only people who have a pronounced affinity for dogs would consider them an image close to epicski, it's ethnocentrism. I tend to think the less is more tact is best as a public face, which is what the stickers are.
Epic Ski: All things skiing.
How about a Saint Bernard with a whisky casket around it's neck?
An EpicSki dog bumper sticker on my truck camper would look great. After all in winter it is my mobile ski chalet- heated dog house for Tia the swifer mop dog. I will take several.
