When my kids suggested going back to D.C. for vacation this year, I had to make sure we saw and did things that we didn’t do 2 years ago when we visited. So, I got advance tickets to the Washington Monument. Tickets are normally free, but the line can start at 7am for that days tours. Rather than take a chance on missing out, I paid $1.50 apiece to guarantee my tickets, a pittance in my book. As it turned out, even paying the $6 was a steal for the view.
