VB, like nearly every county & city nearby is trunked. Be sure you take a compatible scanner with you. Most are Type II analog Motorola, except for Chespeake (Motorola digital) and Hampton (EDACS). VBEMS dispatch is still simulcast on VHF if you're interested in that.
The Hampton Roads Scanner Page is up to date with the latest active info. Check the link in my signature below. Also, check out the ham repeater listing page at my ham site: www.qsl.net/kc4jgc/ .
