I’m sure this is way too early to be thinking about logistics … but when you start to think about how to get the thing onto a truck, off of a truck, to Oak Point Park, etc., there is one little thing you need to know.
Oak Point Park (the Slingfest location) is in a flood zone (next to Rowlett Creek). The creek frequently overflows covering several hundred acres. The Slingfest location is the area shown in the video starting at approx. 0:13. It routinely has a foot or more of standing water after heavy rains, and that water sometimes sits for a week or more depending on the rain. Right now there are still large areas standing in water three days after Sunday afternoon’s rain. While I’m not suggesting that you will be firing in standing water, if it has rained during the month of October that big field could very well be marshy / boggy / swampy.
Might want to give a little thought about how you would wheel it across and or set it up on very soft, waterlogged ground. I’m seeing plywood …
