I have been climbing, roaming, entering for basically ever, i have an interest in multistory build and cranes, howver am discovering drains around Melbourne, i have entered a few i have found from clues online; but would like some more direction or recommendations, i have entered clan cave caves and tried making contact there.. i even sent the $10

I tend to explore alone, namely because i didnt really realise it was a scene so would be interested if there are ever group activities.
most drains ive entered appear to be quite dormant; dated graf etc. but i havent done some of the more famous ones, just ones ive come across...
anyway thanks
