Go today instead. Been wanting to take your mountain bike in for its annual tuneup ahead of this summer's riding season? Take it in today. Fill up your tank this afternoon. Take your family out to eat. Go book shopping. Concentrate your weekly discretionary income spending into today. With less immigrants in stores and on the roads you'll be safer and there will be less traffic congestion. Show the illegals and their socialist backers that they are not needed.
