Back when I was a teenager a group of us were in service. First of all you've got 4 teenagers riding around in a car together, unchaperoned and unsupervised...but hey...it's okay...we're in Field Service.
Anyhoo, we were working out in the middle of nowhere (by design - very few houses to get in the time we were out). We were on this old dirt road, but well traveled even though we didn't know of any houses. We followed it, ignoring the huge hand painted, "No Trespassing - We Will Shoot" signs posted on each side of the road.
We came around the bend and there we found an old ranch style house with a long front porch. But parked outside the house were at least a dozen motorcycles. As we pulled up...too late to turn around... several bikers came out, a couple of them armed. The obvious leader came out to the car. We thought about just telling him we were lost but after a brief discussion...all the while he's walking to us...we figured it was safer to tell em what we were doing...and we were right.
Two of us got out and talked to the guy. He was huge. Long hair, beard, tattoos, leather vest, dirty jeans, chain wallet. Typical biker. The nicest guy, though. He was pleasant, especially when he realized we were selling religion. After our presentation, he just kinda chuckled, looked back at the house where the lookouts were making sure we saw their firearms and just said, "Well, I guess it should be obvious that we're not interested". We chuckled, more nervously than him though, and thanked him for his time. As we were leaving, he wished us a nice day but warned us to not ignore their signs next time.
