The date is set for April 18, starting in Concord at 4pm (Exit 2 off 393, near East and West Sugar Ball).
Let me know what your teams of four are. My brother Jonathan and new son Kyle are both available as team members.
I have Concord area maps that include the proper locations in Concord and Bow. I recommend a good state map, a compass unless you can find south on your own, pencils and scrap paper, and whatever reference materials you want. Laptops are allowed.
