Most of the surrounding area is state land cultivated with wheat, with occasional fallow fields or rocky uncultivated areas. The terrain is slightly rolling, with few fences.

Please make sure your children are aware of the hazards associated with rattlesnakes. Ticks can also be an issue - please be aware of mitigation & inspection procedures.

Logistics:

Mansfield has a grocery store and bar. The grocery's hours were posted as 8 am - 5 pm on Saturday and Sunday during our site survey. The bar serves food, but individuals younger than 21 are not allowed inside. They will make up takeout food, and the grocery store makes sandwiches. The gas station in town is open during the day, but it is best for folks to fill up in Waterville or down in the valley on the way in.

Potable water is not available at the site, but it is in town (roughly 2 miles away). Please plan accordingly, and bring plenty of water.

Due to the dry nature of the area, open fires & fireworks are not permitted at the launch site.

Concessions & Porta-Potties may be available at certain launches

Several of us had good cell phone reception on the Verizon network while on the site survey.

Lodging:

The town of Mansfield has no lodging, but an un-verified list of regional hotels and campgrounds is available. During the Memorial Day weekend, lodging is likely to be scarce. Overnight camping is available at the site, with some restrictions. Please talk to the person at the check-in/Pad Manager table for details.
