Thanks for all the advice. Bigger is better but more work. Once I start flying again I will get a better idea as to length. Two hundred fifty may be reasonable. I cut an 8' path at 3" in pasture behind my house and it did not look too bad. So 2- 21/2" may work provided it is nice and level. Once the final hay cut is done I will get the transit level out and layout and mark a runway. See how it looks. Having the pilots station at runway threshold will let me bring the airplane in ready for touchdown.
As as for a club I do plan to join a club. There I can find an instructor, meet other pilots and join in periodically as time permits.
