I live in Northern Virginia now and sold off my dirt bikes. My brother just scored an '83 Honda Z50R to restore and give to my kids for Christmas. By then the oldest will be just over 4 years old. I don't have room on my .5 acre lot to let him roam around. Are there any open fields that it's legal to run a kid on a 50cc dirtbike nearby? I googled some ORV parks, but they're too far away for a toddler's patience level.
