Looking for opinions for a park to be built in Plymouth, Nh,I93, right off of exit 26. what should the ramps be and sizes of. also possible bike ramps, jumps,etc possibly intergrated within board park. If not there is room for piles of dirt in the rear of planned board area. May start small, with provisions for larger additions, with the possible biggie big half pipe??!! I am searching for an concept idea, because the people in area,that want to build it, do not know much on topic. any help greatly appreciated. the sky is the limit?? ra
