Traveling to AM worlds with my twin boys, 11 yo, so will need some kind of babysitter at times during the week... Someone who can hang out with them while I play. Skateboarding, at the pool, etc... I bought three spectator passes so you can come and see the tournament as well. They speak English very well. So all tips regarding this are very appreciated!
Check out craigslist - Us - Arizona -flagstaff/sedona - community - childcare. Im sure you can find someone.
If you're on facebook, you might consider joining the Flagstaff Disc Golf Club page and post on there. Many players have kids about the same age as your sons and might be able to help.
