I live in Longmont, CO. about 35 miles north of Denver. There are anumber of lakes around here but, most are small. Glencoe, WY seems to be the closest hot boat hang out. I haven't been there yet. I just moved here about a year ago from Dallas and my boat isn't finished yet. I think Glencoe is about 200 miles from Denver but, not positive. To the best of my knowledge the lakes close to or in Denver have 40 MPH speed limits and some enforce them ridgedly. Sorry I can't be more help but, I haven't actually been out on these lakes yet.
