Take a trip to MD's Anne Arundel County area - specifically, Glen Burnie, Pasadena and surrounding suburban areas.
You should have no trouble rounding up a good 15-20 of them, especially in the spring and summer - there's always been a bit of an entrenched crowd of all ages due to MD's total scam operations dealing with cars.(tags,title,license,inspection,emissions,hassle,hassle,hassle, $$$, $$$, $$$)
In order to even put a heap on the road, between all of that is $4,000.00 + and for a 'ped all you need is the K-permit, 20 bucks to pay for it, and a quick law test.
So you have a lot of them just south of Baltimore in the safer suburban riding areas, just a matter of finding them and getting them interested.
