Besides riding on water we also kite on land, typically in large soccer fields/complexes with plenty of open room for free flowing wind and nothing to hang kites up on. One favorite local landboard spot is west of Haysville jr high school on south Meridian ave (south of Wichita south of I-235). See the map below for detail info. Enter in by the water tower (bus storage) and we park and rig up between soccer fields (blue circled area). Entire red marked area is landboarding area.
Locally we water kite whenever possible, but there are times (rarely) we kite onland. Ground hurts when fall, crash, or unexpected gust drags ya. When we do landboard, it's in the winter time (dec-feb) when or if the lake freezes over, and when there is no snow on the ground to snowkite. Pads, gloves, helmet, and plenty of protection helps (why rather do in colder seasons). Below video what is possible on landboard freestyle.
There are times we have correct conditions to snowkite locally. Because we don't get snow often enough, there is never a snow base. With usually only 1-6" of snow per fall, our snowboards can dig into the ground when edging. You can also use snowskis to snowkite with. Again we choose open soccer fields to snowkite on. We only get a hand full of snowkitable days per year, or some years don't have any days to snowkite. Snow usually only lasts a few days (weeks tops) before it all melts away. So only real time to snow kite is during a snow storm or a day or 2 directly afterwards, if the wind blows. Typically to be decent conditions to snowkite, the snow needs to be slighly wet to stick to the ground when the wind blows. If the snow is a dry condition it blows away in the open fields we want to kite on and drifts to locations we can't safely kite. But if the conditions are right, we do get some snowkitable days here. What we have found to work the best with any snowboard, is rear entry bindings (picture below is open and closed) to get in/out of very easily rather then the traditional ratcheting style bindings. The specific manufacture of these bindings is 'flow'. Reason we choose flows over traditional ratcheting bindings is trying to get in/out of traditional bindings while flying a kite is a mess, especially in gusty wind conditions.
Note: I personally found snowkiting with my seat harness works better to help keep the spreader bar down below my coat. With a waist harness, you put it on underneath your coat, but you have to lift your coat up to expose your spreader bar to hook in. Then the spreader bar rises up exposing more midsection skin, and in ice cold windy snowkiting conditions it sucks freezing your stomach! There are jackets/coats available specific to snowkiting that has a spreader bar hole in middle of the coat. Your harness will be on under your coat and will keep your midsection warm while you are hooked in kiting. But for our area that we rarely snowkite, it's not worth the investment (those coats are not cheap). Unless you know how to run a sewing machine, then cut away on your winter coat, and simply sew in a zipper for your spreader bar hook. I just found using seat harness works good.
