HI Blobsquatch,
I was on Tim Lake with my 5 year old son, two friends and their little guys as well. The three adults were woken up at 3am to a massive thunder storm and torrential rain. How the kids all slept right through the storm i'll never know, the thunder was really shaking the tent. The really cool thing was we heard some wolves howling between the thunder. We all stayed dry until we were packing up around 9am.
Glad to hear you were better situated than we were.
Jeff
