A ground breaking ceremony will be held this week for the off leash dog park in Danbury.  The fenced in park will be on four acres of land off Miry Brook Road, by Danbury Municipal Airport.  The only restriction is that dogs are licensed.  The park will be for daytime use only and have limited parking. No one will be staffing the park.  A sign will be posted saying that aggressive dogs are not allowed.  Plan calls for cleaning out the undergrowth and planting grass seed.  The ground breaking is set for Tuesday.
