Even if you don't want to use Adsense, it would still be good for testing purposes.
If you're only making a few pennies with it, it could be a sign that you are lacking the traffic and/or content that would make ad space attractive to businesses you'd approach.
On the other hand, if you make a bunch of money with it, then you now have a good idea of a minimum to charge. If a business is willing to pay more for a spot on your site than Adsense is generating, there's no reason not to do it.
And if they bail, you'll know that you can pop the Adsense code right back in and still have an income while you look for a new advertiser.
Another option would be to open an account at cj.com and search for affiliate programs that are related to your content. Not just skateboarding--but other areas that skaters would also be interested in.
In the right conditions, an affiliate program can generate a lot more than ads.
