Dear local entrepreneurs,
At the last Oberton Community Council meeting, town residents voted to install an outdoor swimming pool on the grounds of the Oberton Community and Recreation Center. However, we need your help in order to make this resolution a reality.
Beginning August 1st, the Oberton Community Council will be collecting donations from area businesses. There are three contribution levels, and contributors at each level will receive recogni-tion and prizes as specified below:
Level 1 ($50-$199): A mention in the monthly Oberton Community Newsletter
Level 2 ($200-$499): Above + a gift certificate to an area restaurant
Level 3 ($500+): Above + a reserved seat for the opening ceremony for the new swimming pool
Remember, Oberton residents are counting on your support! For information on how to con-tribute, contact me directly at 555-2911, or simply mail your donation in the form of a check or money order to the address at the top of this letter.
Thank you,
Bruce Healey
