    Need directions to Bragg farm.
    Thanks Dan. Also have other club info to share.

  3. Awesome website you have here but I was curious if you knew of any
    discussion boards that cover the same topics discussed here?
    I’d really love to be a part of community where I can get responses from other knowledgeable individuals that share the same
    interest. If you have any suggestions, please let me know.

      Assuming you’re not in the Huntsville Area and can’t make it to one of our club meetings, there is an active online community that encompasses Low-Power (model) and High-Power (sport and research) rocketry both here in the US and internationally at:

      It is an unofficial discussion board, but it is frequented by experienced rocketeers at all scales of the power spectrum.

  4. Believe that you have it inside you to reside in for a fullest potential.
    You can also devote some time when you do repetitive tasks which don’t require your full attention to focus inward.
    Almost people have found out about tales where people were
    scheduled to visit on a certain airplane or ship and changed their mind with the last moment since they felt funny
    about it.
