all mountain shirt designs

looking for any imput from some all mountain singletrack riders. Any ideas for some new t shirt ideas are appreciated. We just put the sight up and really want some feedback so we can make things grow. We started out buying used bikes off of craigslist and ditributing them to kids through our lbs but if we get some shirts sold we are going to buy trail worthy hardtails for around $800-$1000 each. help us get kids out of the house and start shredding some singletrack! www.ilovesingletrack.com
