Hey /out/ my friends and I recently got an interest into exploring drainage pipes. For some reason we think its pretty cool and we like to check out the graffiti in there plus you never know what you're going to find. We have already explored most of them in our area and we need to know how to find some more. Do you guys think you can help us out by giving us some locations or information on how to find them? We live in Hooksett New Hampshire but anywhere like Candia would be okay to explore. Thanks in advance.
