need help in PN

I need suggestions and helpful info on Piedra Negras, as it is in driving distance for me. I've been to NL often. So, I'm familiar with this Texas/MX border.

So, I would like to solicit some suggestions by PM (or here on the forum). And, also, whether there is a better website to help me start up there in Acuna, and avoid trouble too.

I'm interested in meeting up with anyone from here as well, when I visit in about 2 weeks.

Please list some websites that are good for this city here and PM me with more specific suggestions. Can someone please summarize the general approach to this border city?
