Hi there! I'm down the road a bit in Hartlepool.
You've got several sites in the area:
NSC near the airport. Woodland gaming on a Paintball site.
No limits - indoor CQB in Gateshead
NTAC - small woodland site near Pittington
Dirty dog - probably the main site in the area, a container village with woodland and open ground. Located at Shildon
District 23 - similar to no limits. Billingham by the train station.
Adrenalin - another Paintball site, near Richmond.
Stirling airsoft - themed airsoft that tends to run weekend events around once a month, set on Catterick army base.
