Think you have what it takes to survive a natural disaster, military invasion or like, when hostile aliens come to harvest our natural resources? Survivalists of all stripes will be out in force for the Greater Richmond Survival Expo from on Saturday, March 25, at the Richmond International Raceway, 9 a.m.-5 p.m., and again on Sunday, March 26, 9 a.m.-4 p.m. Vendors will hawk wares for long-term food storage, solar power, bug-out kits and tactical gear. Children get in for $5, adults are $12 (with VIP options for those who can’t wait in line). rkpreppershows.com.
