LPG/NGL

General post re LPG/NGL market - curious to hear thoughts on current state of LPG/NGL market. This portion of light-ends spectrum has been strong in the face of overall weakness in market over the past 6 months. Would be interested in hearing thoughts regarding why this may be the case as usually related markets (gasoline, nap) have seen weakness not dissimilar to that of crude. How do we see this market faring over the next 6-12 months? Can suggest sources of information that are widely referenced in gleaning market color? Also, anyone familiar with LPG freight? Look forward to responses.
