In a recreational activity accident such as your daughter's tubing accident, we would need to conduct a site inspection of the course or slope that she was on. The inspection would determine whether the course was designed safely for use. If the course was not built safely and often led to accidents, the establishment and/or owners of the place may be liable.
Further, if the establishment had notice of prior injuries due to the dangers on the slope or course and did nothing to correct it, the establishment may be liable for your daughter's injuries as well.
With that said, I would need more information regarding your daughter's accident, such as where it happened, when it happened, the weather conditions that day, etc. The above answer is a general answer based on your question.
Please contact me or my colleagues, who have represented many individuals injured in recreational activities in Pennsylvania and New Jersey, to discuss your daughter's accident and legal rights. 877.944.8396.
