Please join as there is need for help in all levels. If you lack in phyisical abilities..thats fine as there are so many positions to post that don't require strength or endurance.
Our County has tried developing its own SAR and we can never seem to get it off the ground. The Duty falls upon the local Fire&Rescue departments, and the County Sheriffs. They have the equipment already, train specifically for SAR and already have the best Command structure in place.
We will train mutually with all National, State and County agencies...and when SAR is needed..we are deployed through our Central (911) dispach. Our Emergency Services Coordinator heads our Command. Our County Sheriffs and Fire Dept. are first to respond...and as the need arrises...further Mutual aid expands from there.
Eventually, the need for a County SAR unit will be necessary....and in past attempts to make this possible...those responding, and training were represented by Fire& Rescue, Sheriffs, National Park Service, State Police, and Red Cross. In actual events or training evolutions...it has also included Coast Guard, DNR and Local Police as well.
We have such good responses from departmental agencies..and all understand the need for a "command structure" and working as a unit...we have been very successful. Occasionally we have civilian help...and their efforts are equally important.
However your County works its SAR service...I highly recommend getting involved. Someone lost or in peril.....the need to respond or help in any way is immeasurable. Even if you decide to help as a civilian...gaining some training and knowledge is very important. Our worst nightmare is having to SAR one of our own members. Ofcourse...you will not be asked to exceed you skill level, ever.
Obvious equipment for hiking, flashlights, season appropreate clothing, a day pack, compass, your County topo maps, a GPS, cell phone, and saddling up a horse is good..ATV, snowmobile, boat..what have you. Resources are always in demand. Many of us keep a SAR pack current and ready in the trunk of our POV. When you get "on scene" you can adjust as needed. If you happen to own extra gear...bring it...someone always will benefit...thanks!!
Ofcourse, land, water, ice, rope, etc. rescue requires specific training. Find what your skills offer most, and go in that direction. And also, as you suggested you have limited physical ability...no matter...its a team effort, and every one is an equal, and can share equally in the success.
