Took the family camping and it rained the entire time
We went to try out this new campground about 2 hours out and the weather forecast was totally wrong. Rained from Friday night straight through Sunday morning. The tent held up great at least. My wife was mad we couldn't do the hiking we planned, but honestly the kids thought it was an adventure. We played board games in the tent and made s'mores under the awning. Sometimes the best trips don't go as planned.
Man that sucks but those are actually the best stories later. My family still talks about the camping trip where we got soaked and had to use the camp office to dry everything. The weather being bad forced us to bond harder. Check back next year when the forecast looks perfect.
Weather forecasts are never right when it matters. At least you tried something new though. The kids probably remember it more than if everything went perfect anyway.
