The street address of the Prude Ranch is:

Plan your trip to arrive at the ranch before 7pm without an RV and 6pm if you are RVing, if you are staying on the Ranch or intend on setting up a telescope.


Once you arrive at Prude Ranch, there is one main entrance.

You will have to stop at the front gate and have your Registration for TSP 2023 verified and screened for Covid-19. Our TSP Front Gate Team will compare your Photo ID against our Registration List and Database to confirm you are registered.  Complete any Covid-19 Waiver and General Liability forms you have not submitted online, by email, or simply hand to a Front Gate Staff member your previously completed and signed forms listed above. You will  be issued a TSP 2023 Event Wristband that must be worn throughout the entire Star Party.  If your wristband becomes damaged, you can return to the Front Gate and turn it in for a replacement. Any attempt to remove will destroy the wristband.  Everyone attending, will have to wear a wristband to be on the ranch.  Anyone without a wristband will be asked to leave the ranch. If you are a registered attendee, the Front Gate Team will verify your registration etc… and issue you a wristband. Thank you..

After you have been processed by the Front Gate Team, the next place you will go is to the Ranch Office or an area determined by Ranch Staff (Covid-19 Protocols will be in effect), located in the central compound (1/4 mile drive from the main gate). This will be to check-in, get a site map, and make payment of your Ranch Housing Accommodations.

The Dining Hall is adjacent to the Ranch Office. The TSP Meeting Hall (and TSP Information and Sales Desk) are located behind the Dining Hall. TSP Vendors are located in either The Lodge (north of upper field), The Pavilion (middle field) and/or the Upper Field Demonstration area. The TSP HAM Radio and HAM Staff building is located next to the tall radio antenna tower.

NOTE: TSP Registration is now part of Front Gate Check-in.  Ranch Check-In conducted at the Front Counter of the Ranch Office and separate from TSP Registration and Front Gate Check-In that you may do. Be sure to stop at the Front Gate to have your Registration verified before you enter the ranch. Do not enter the ranch property if you have not been processed by the Front Gate/Registration Team. The Front Gate Staff will issue you a colored TSP Wristband which you must wear at all times during TSP Week.  Anyone found to not be wearing a TSP Event Wristband will be escorted off the ranch and will not be allowed onto the ranch until their registration for TSP Week has been confirmed. Anyone wearing a wristband that appears to be damaged, taped together and/or stretched will be escorted off the ranch.  Go to the TSP Sales and Information desk to pick up important TSP “stuff”! If the Front Gate is not staffed when your first arrive at the ranch, do not enter the ranch property.  Your registration must be verified and your wristband issued and attached to your wrist before you can enter the ranch.

IMPORTANT! Staying offsite or arriving/departing after 9 PM?
There is no driving on the Ranch at night (due to lighting ban and safety issues)!

The front gates of the Ranch are closed at 9:00 PM to restrict traffic and minimize disturbance to observers. DO NOT plan to arrive to set up at night. Park your car outside the gates (view picture) if you plan to leave during the night.
Use care when parking on the public roadway. Attendees often back-in park (pointing headlights to roadway) to ease departure.
Watch out for road signs and reflective marker posts.
