My favorite seasons in RVA are summer and fall.  There are a lot of reasons behind this but downtown events are plentiful during these periods — and in many instances these events are free!!  My go-to source for  exploring and scheduling free time events in Venture Richmond. Here is a great link to bookmark for activities!  http://www.venturerichmond.com/events/calendar.html.  Or of course you can always go exploring on a Segway which I recently did with my daughter!
