Have decided to purchase a boat and would appreciate any suggestions and advise. I live in Denver, CO and have access to a couple public lakes, however will probably do most boating at Lake McConaughy, NE and maybe Glendo, WY (other suggestions close by welcomed). The family will learn skiing, wakeboarding (have a 6 and 3 year old boys), cruising is secondary and no fishing. Probably buying used with a budget of <=$20K. Thanks.
